I'd like to lower my car, are there any springs available for the Protegé?
I want to get new shocks while I'm lowering my car too, are there any?
What tower bars are available?
Are there any sway bars for the Protegé?
What does the MP3's sway bar kit comes with?
What does the MazdaSpeed Protegé's sway bar kit comes with?
I own a 3rd generation Protegé and would like to get the MP3's tower bar.
  What do I need to get?

What's the part number of the Protegé 5 front tower bar?
What's the part number of the MazdaSpeed Protegé's front tower bar?
My (stupid) dealer got my tower bar all scratched up, what can I do to make it
  not such an eye sore?

Everywhere I look, they only have front tower bars for the 3rd generation.
  Where can I find a rear tower bar?

What about "lower tie bars"?
What suspension settings should I use?
Are there any suspension bushings available?
What are the wheel bolt on paterns for the Protegé?
I am going to get larger/smaller aftermarket wheels for my car, will it affect the speedometer?
Can suspension parts from foreign 323/Familia models be used to improve the
  performance of my BJ chassis Protegé? What about MP3 parts?

Can any wheels from other Mazdas or Fords be used as an upgrade on a Protegé?
I need wheels for SCCA Solo II Stock-class autocrossing. What are some good,
  inexpensive choices other than a set of stock Protegé wheels?

I am performing an alignment on my MP3. Are there any special settings?
I am performing an alignment on my MazdaSpeed Protegé. Are there any special settings?
What is camber, and what effect does it have on handling?
I’m going to lower my Protegé and I’m concerned about camber.  Will lowering my car
  increase camber too much and cause a tire wear problem?

How do I adjust my Protegé’s camber?
What is caster, and how do I adjust it? What are the effects of more or less caster?
What is toe, and how do I adjust it? What are the effects of toe-in and toe-out? Will lowering my car
  affect the toe?

After I replace the struts and/or springs on my Protegé, do I need an alignment? Is there any way to
  avoid it?



I'd like to lower my car, are there any springs available for the Protegé?

I own a 3rd generation Protegé and would like to get the MP3's tower bar.
What do I need to get?
    Mazda USA has released the MP3 tower bar kit which includes all the required parts.
    For cars with cruise control, the part number is: 0000-88-C07_-KT and for cars
    without cruise control, it is 0000-88-C08-_KT. Both kits should cost $165.
    If you live in a country that does not yet have the kits available, you may get the parts
    separately (which will cost you more). Additional parts you need are sourced from the
    removed stock parts.
    Part numbers and dealer prices as follows:
      Bar (yellow): BN7H-56-49X, $175.70
      Right bracket (cruise control compatible): BN5V-56-5CX, $32.55
      Left bracket: B28V-56-5DX, $29.55
      Mounting nuts (4 needed): 9994-01-003B, $1.60 each
      Boost (vacum) sensor bracket: FS8M-18-835, $6.72
      Bracket nut (1 needed): 9989-10-600, $1.35
    The following is needed for cruise control models:
      Bracket nut (3 needed): 9989-10-600, $1.35 each
      Cruise control bracket: BN5W-66-3AY, $14.35
      Rubber bushings for cruise control bracket mounts (2 needed): B6S7-13-349, $5.85 each
      Mounting guides for cruise control bracket mounts (2 needed): UE54-66-3A5, $4.70 each
      Mounting plate for cruise control bracket: BN5W-66-3B2, $4.70

    Sternly state that you want the tower bar wrapped up when the Mazda parts
    distribution center sends it to your dealer!



What's the part number of the Protegé 5 front tower bar?

    You will need to get everything listed above, but substitute the bar with
    part # B28V-56-49XE. This bar is in red color.


What's the part number of the MazdaSpeed Protegé's front tower bar?
    You will need to get everything listed above, but substitute the bar with
    part # BP7H-56-49XE. This bar is in silver color.


My (stupid) dealer got my tower bar all scratched up, what can I do to make it
not such an eye sore?

    Short of repainting the whole bar (which will cost some money and a body shop
    to order paint), you can talk your dealer's parts department into giving you
    a free bottle of touch up paint. The tower bars are painted the same colors
    found on the Protegé 5, so things will be a lot easier at least.
    The MP3's tower bar is painted in Vivid Yellow. The color code is HZ.
    The Protegé 5's tower bar is painted in Classic Red. The color code is A3E.
    The MazdaSpeed Protegé's tower bar is painted in Sunlight Silver Metalic. The
    color code is 22V.


Everywhere I look, they only have front tower bars for the 3rd generation.
Where can I find a rear tower bar?

    The 3rd generation Protegé 4 door has the rear strut towers already braced;
    it is actually part of the unibody. It is quite big and should offer lots
    of reinforcement. The Protegé 5 does not have the rear brace as part of the
    unibody due to its hatchback configuration. Unfortunately there is not a
    known aftermarket company in the US that makes a rear bar. Talk to
    an aftermarket company to consider making one. The only known solution
    for the Protegé 5 at the moment, is importing the AutoExe or Okuyama
    rear tower bar.


What about "lower tie bars"?
    For 1st generations:
      Infini rear bar (part #: B595-28-671A)
      MX-3 V6 rear bar (part #: E018-28-671A)
      SRD rear bar
      Cork Sport front bar
      Cusco Type I lower arm bar
    For 3rd generations:
      Autoexe lower arm bar
      Autoexe member brace kit (Australia, Japan, General Market sedans and
       Australia, Japan, Europe, General Market wagons only)
      GT-Spec lower braces
      Cusco lower arm bar
    For Mazda3:
      Autoexe member brace kit
      GT-Spec lower braces
      Ultra Racing member braces


What suspension settings should I use?

    Ultimately, you should strive for a neutral handling car. It is not
    impossible, but it is quite difficult (Honda did it with the Type-Rs,
    Racing Beat done it with the MP3) to do so. It is definitely impossible
    and a no no if you don't know how a suspension system works. And as usual
    our Nissan friends can answer all of our questions about suspension tuning.
    Suspension is suspension, it is not car specific other than the actual
    design. However, setting theories and terminologies applies to ALL cars.

Are there any suspension bushings available?

     Some Energy Suspension bushings meant for the Escort are compatible with
     the 1st generation Protegé. Whiteline also has bushing kits for the 1st and 2nd
     generation Protegé's. MazdaSpeed also has some bushings available.
     The part numbers for the 1st generations are:
       B1Y1-28-775 sway bar end link bushings, 4 needed per end link
       B1Y1-34-46X front right lower control arm bushing (rear)
       B1Y1-34-46Y front left lower control arm bushing (rear)

       B1Y2-28-156A front sway bar bushing (23mm)
       B1Y3-28-156 rear sway bar bushing
     MazdaSpeed makes some bushings for the 2nd generation Protegé's also.
     The part numbers are:
       B0YA-28-620 lateral link (front)
       BCYD-28-600 lateral link (rear)
       B0YD-28-200 right trailing link
       B0YD-28-250 left trailing link

       BCYD-34-46X front right lower control arm bushing (rear)
       BCYD-34-46Y front left lower control arm bushing (rear)
       BCYD-34-156 front sway bar bushing (25mm)
       B0YC-28-156 rear sway bar bushing (20mm)
     There are only a limited selection of bushings available for the 3rd generation
     Protegé's. Delsing Motorsport makes adjustable pillowball front upper strut
     mounts as well as "klunk fix" rear sway bar bushing relocation brackets
     (includes new bushings). Adjustable rear sway bar end links are available from
     Delsing Motorsport as well as AWR. AWR also makes the following bushings:
     trailing links, lateral links, adjustable pillowball front & rear upper strut mounts,
     front lower control arms (featuring spherical bushings). GT-Spec also has
     trailing links available. The 2003 Sport20 special edition and MazdaSpeed
     Protegé also came with stiffer front upper strut mounts. The part number is
     C145-34-380C. All S-Wagon Sport20's and MazdaSpeed Protegé's also came
     with trailing links that have stiffer bushings.
     The part numbers are:
       B30J-28-200B right trailing link
       B30J-28-250B left trailing link

     Some 3rd generation owners who have upgraded their suspension have been
     experiencing clunking noise from the rear right area. The noise is actually due to
     the strut piston floating momentarily because of the excessively soft rear upper
     strut mounts. A work around remedy for many people has been the addition of
     two M12 washers above the factory retaining washer in order to place more
     clamping force between the strut piston and upper mount while still using the
     same fastener travel. When tightening the strut piston nut, DO NOT over
     torque the nut or use any air/power tools to tighten it! The retaining washer's
     metal is extremely soft and over torquing can force the positioning keyway in
     the retaining washer to break! 3rd generation sedan owners are encouraged to
     upgrade to the Protegé 5's rear upper strut mounts as they are slightly stiffer.
     This will not only improve handling characteristics, but will also ensure greater
     chance that there will be no clunking noise. The alternative of course is to
     simply upgrade to the pillowball mounts AWR makes. The Protegé 5's rear
     upper strut mount part numbers are:
       BJ3D-28-380 rear right upper strut mount
       BJ3D-28-390 rear left upper strut mount
     They can be easily identified by two longer mounting studs out of the three.
     The short mounting stud is the same length as all three on the sedan's version.
     The additoinal mounting stud length will pose no concern to clearance issues
     rest assured. If the clunking noise persists, then the only other possible
     problem is the spring coils hitting each other. This occurs with some after-
     market springs that have some spring coils spaced closely to each other. The
     solution to this problem is to install rubber sleeves/wrappers over the culprit
     spring coils. Some spring manufacturers, such as Tein sells such products.



What are the wheel bolt on paterns for the Protegé?
     All 4 lug Protegé's use a 4x100mm bolt on patern and 5 lug Protegé's use a
     5x114.3mm patern.


I am going to get larger/smaller aftermarket wheels for my car, will it affect the
speedometer?

     Yes, it will affect the speedometer due to the new overall final drive ratio. Put it
     simply, larger wheels will result in a speedometer reporting a slower speed while
     a smaller wheel will result in a faster speedometer reading. Our Miata friends
     over at miata.net have made a nice tire/wheel size calculator page to help you
     choose the correct tire/wheel size combination for a more accurate speedo-
     meter reading.
     Go here for the calculator page: http://www.miata.net/garage/tirecalc.html


Can suspension parts from foreign 323/Familia models be used to improve the
performance of my BJ chassis Protegé? What about MP3 parts?

    Yes, please read below for a detailed explaination.

    The stock suspension for the BJ Protegé can be roughly categorized into 4
    groups: Normal, Hard, Sport and MP3/MSP.

    The “Normal” suspension has been used only on cars bound for Asian/Pacific
    countries.  It uses softer springs, no rear sway bar, and a smaller front sway bar
    than U.S.-market cars (the actual diameter of this swaybar has not been verified).
    The small front swaybar from this model may be useful to reduce understeer for
    competition in SCCA Solo II Stock-class competition. Other than this swaybar,
    parts from this suspension are probably of little use to U.S. and Canadian
    enthusiasts.

    The “Hard” suspension uses a 20mm front swaybar and a 17.3mm rear swaybar
    for the 1999 cars.  The rear swaybar was reduced to 16mm in 2000. The front
    swaybar has been increased to 21mm in 2001, possibly to further increase
    understeer "safety" handling. This suspension has been used on DX & LX U.S.
    and Canadian-market BJ Protegés. Some models use different lengths of springs
    to keep the ride height uniform between cars with different combinations of
    optional equipment. However, the spring rates are always the same; the only
    difference is the length.

    The “Sport” suspension has been used on various European, Japanese,
    Asian/Pacific 323 and the 2001+ ES and P5. It uses slightly stiffer (by ~15%
    than "hard") springs and struts than the “Normal” suspension. The front sway bar
    is also larger (22mm) and the rear sway bar is 17mm. The front sway bar has
    been increased to 23mm in mid 2002, probably also to increase understeer
    "safety" handling.  Ride height maybe slightly lower than the “Hard” suspension.

    The MP3 suspension uses stiffer springs (10% stiffer than "sport") that lower the
    car by about 15mm, a front strut tower brace, stiffer Tokico struts, and larger
    swaybars- 25mm front, 19mm rear. Parts from this suspension may be used to
    upgrade lesser Protegés; however, the swaybar endlinks on a BJ Protegé attach
    to the struts, and the MP3 uses stronger brackets to accommodate the stiffer
    swaybars (see Racing Beat's site for more information).  If you use MP3 sway
    bars without the matching MP3 struts, be prepared to reinforce the strut brackets.
    The MazdaSpeed Protegé's suspension design is based off of the MP3's suspen-
    sion. It uses even more stiffer springs and Tokico struts. Because the suspension
    design is based off of the MP3, the problems mentioned above also were inherited.



Can any wheels from other Mazdas or Fords be used as an upgrade on a Protegé?

    Wheels from any Miata or MX-3 will fit perfectly on any Protegé except for the
    2001+ ES and Protegé 5, which have 5 lug wheels. Miata alloy wheels are
    generally lighter than Protegé wheels and make an excellent performance upgrade.
    The 16” wheels offered on 2001+ Miatas are the only stock Mazda 16” wheels
    that will fit on a 4-lug Protegé.  Wheels from a Ford Escort GT/ZX2 will also fit.

I need wheels for SCCA Solo II Stock-class autocrossing. What are some good,
inexpensive choices other than a set of stock Protegé wheels?

    SCCA Solo II Stock-class rules require wheels that are the same width and
    diameter as stock. Offset must be within ¼” of stock.  There is no restriction on
    material, weight, or type of wheel. There are several readily available, inexpensive
    wheels from other cars that will fit most Protegé's.

    The BG chassis LX, BH-chassis LX and ES, and BJ-chassis DX and LX 1.6l
    use 14 x 5.5” wheels with a 4 x 100mm bolt pattern.  The best wheels for these cars
    are 7 spoke stock wheels from a 90-93 1.6l Miata.  These wheels have the same
    bolt pattern, offset and center hole diameter as stock Protegé wheels, but they are
    significantly lighter.

    Another good choice are Honda wheels. 14x5.5” alloy wheels with a 4x100mm
    bolt pattern and 45mm offset have been used on various late 80’s and early 90’s
    Accords, Preludes and Acura Integras (stock Civic wheels are either too narrow or
    only available in steel).  Honda wheels are not hubcentric on a Protegé (although this
    is not as critical for autocrossing as it is for street use) and they are heavier than
    Miata wheels.

    The BJ chassis ES 1.8l and DX/LX 2.0l use 15”x6” wheels with a 4x100mm bolt
    pattern and 45mm offset.  The most obvious wheel choice for these cars are Miata
    wheels from a 95-97 Miata M-Edition, 99-00 Sport or Leather Package, or 01+
    base model. 95-97 Miata wheels have the correct offset (45mm) and the 95 M
    Edition BBS wheels are the lightest of the bunch; 96-97 M-Edition wheels are
    heavier.  99+ wheels have a different offset (40mm) but the 5mm difference is
    within the SCCA’s ¼” allowance. These wheels are lighter than 96-97 M-Edition
    wheels.

    Another good choice for BJ chassis cars are wheels from a 94-01 Acura Integra or
    a 99-00 Honda Civic Si.  These wheels are the correct size and offset, but they are
    not hubcentric and are slightly heavier than Miata wheels.  However, these wheels
    are abundant on the used market due to the popularity of aftermarket wheels among
    the Honda tuner crowd, many of whom are convinced that the stock 15” x 6” takeoffs
    are worthless and will sell them to you for almost nothing ($100-$200). Wheels from
    a Saturn SC coupe or a 95-98 Nissan 200SX SE-R are also the right size and offset,
    but are significantly heavier than Mazda or Honda wheels.

    The BJ chassis ES 2.0l and Protegé 5 use 16”x6” wheels with a 5 x 114.3mm bolt
    pattern and 50mm offset.  The 89-00 Mitsubishi Eclipse, Eagle Talon, and Plymouth
    Laser RS have been available with wheels that are a perfect fit except for their 45mm
    offset, which is within the SCCA’s ¼” allowance.  Several styles have been available.
    Due to the unusual 16x6” size, there are no other readily available stock-sized wheels
    for these cars.


I am performing an alignment on my MP3. Are there any special settings?
    Mazda never published the MP3's alignment specifications and therefore the only way
    for such information is from the alignment machine themselves, which is known to never
    be 100% acurate. However, according to the MazdaSpeed Familia (Japanese version
    of the MP3) service manual, there are some minor differences in the settings.
    The special settings are:
       Front and rear toe-in: 2.0±2.0mm, 0.08±0.08", 0°12'±0°12'
       Caster angle (front): 2°01'±45'
       Kingpin angle (front): 12°59'
       Camber angle (front): -0°58'±45'
       Camber angle (rear): -0°48'±45'
       Maximum steering angle, inner (reference value): 37°±2°
       Maximum steering angle, outer (reference value): 33°±2°
    Tire pressures must be at 32 psi/220kPa (cold) on the front tires and 29 psi/200kPa (cold)
    on the rear tires as well as a full fuel tank when performing the alignment. Vehicle must be
    unladen (no cargo or passengers) to perform proper alignment.


I am performing an alignment on my MazdaSpeed Protegé. Are there any special settings?

    Yes, the suspension geometry on the MazdaSpeed Protegé must be significantly altered
    from the normal 3rd generation Protegé's to ensure proper handling and reduced tire
    wear. The special settings are:
       Front and rear toe-in: -1.0±1.0mm, -0.04±0.04", -0°6'±0°6'
       Caster angle (front): 2°01'±1°
       Kingpin angle (front): 12°59'
       Camber angle (front): -0°58'±1°
       Camber angle (rear): -0°48'±1°
       Maximum steering angle, inner (reference value): 37°±3°
       Maximum steering angle, outer (reference value): 33°±3°
    Tire pressures must be at 32 psi/220kPa (cold) on all 4 tires as well as a full fuel tank when
    performing the alignment. Vehicle must be unladen (no cargo or passengers) to perform
    proper alignment.


What is camber, and what effect does it have on handling? 
    Camber is the vertical angle of the tires when the car is viewed from the front.  Camber
    is measured in degrees from vertical.  When the tires tilt towards the center of the car,
    this is known as negative camber; when they tilt away from the center, this is known as
    positive camber.  For an explanation of camber, check this link:
    http://www.familycar.com/alignment.htm

    Camber is important for handling because it determines how much of the tires’ tread is
    in contact with the pavement (known as the “contact patch”).  All modern cars with
    independent suspension are engineered to increase negative camber as the suspension
    compresses, thereby maintaining a larger contact patch as the body rolls during cornering.
    Consequently, negative camber will also increase when the car is lowered.  The amount
    of additional camber when the suspension is compressed is known as the “camber curve.”

    Additional negative camber will increase front end cornering grip, but it will also increase
    tire wear at the inside of the tread, decrease straight-line grip when braking or accelerating,
    and decrease straight-line tracking ability. The stock camber spec for a BJ Protegé is 0.5°-
    1.0° negative. 1.5°-2.0° of negative camber will provide good handling without extreme tire
    wear. Hardcore autocrossers and track racers may require 2.5°-4.0° of negative camber
    for maximum front end grip, but this much camber will generally cause excessive tire wear
    and front-end wander on the street.

    Camber also has a large effect on the tendency of a car to pull towards one side of the road,
    especially at high speed. A car will pull towards the side with more positive (less negative)
    camber.


I’m going to lower my Protegé and I’m concerned about camber.  Will lowering my car
increase camber too much and cause a tire wear problem?

    Protegés, like most sedans with McPherson strut suspensions, do not have a very aggressive
    camber curve.  In other words, compressing the suspension on a Protegé will not increase
    negative camber very much- the increase is usually less than 1° for mild amounts of lowering
    (less than 1.5”).  This is good for people who intend to lower their car for appearance
    purposes, or for a moderate handling improvement without creating a tire wear problem.  The
    stock camber spec for a Protegé is 0.5°-1.0° negative, and lowering the car less than 1.5”
    will usually increase camber to about 1.5°-2.0° negative.  This will not cause a big tire wear
    problem unless the car is always driven on straight highways with no hard corners.  Even at
    large amounts of lowering (1.5”+) a Protegé’s camber will usually not increase so much that it
    can’t be easily and inexpensively corrected to less than 1.5° negative (refer to the following
    section). 

    In fact, Protegés tend to wear out the outside of their front tires very quickly when they’re
    driven aggressively, due to their mild camber curve.  If you like cornering hard, 1.5°-2° of
    negative camber will actually IMPROVE tire wear by making the front tires wear more evenly
    across the entire tread.

    If you have lowered your Protegé and you’re experiencing tire wear problems on the inside of
    the tread, CHECK THE TOE FIRST. Toe has a MUCH larger effect on tire wear than
    camber. Many enthusiasts mistake toe problems for camber problems. Do not confuse the two.
    If you are having tire wear problems, get the alignment checked and remove all doubt.


How do I adjust my Protegé’s camber?
    The front camber can be adjusted by removing the nuts at the tops of the strut towers, pushing
    the top of the strut down into the strut tower, then rotating the tops of the struts. You will notice
    that the top of the strut mount is off center in the hole in the strut tower. Rotating the strut so that
    the top of the mount is towards the rear of the car increases positive caster; rotating it so that the
    top is towards the middle of the car increases negative camber. However, there are only 4
    positions, and the range of camber and caster adjustment is only +/-0.5° each way.  Keep in
    mind that you will need an alignment if you adjust the camber because adjusting the camber will
    also change the toe settings.

    The rear camber on a Protegé is not adjustable from the factory except as a side effect of
    adjusting the toe.  The toe is adjusted by rotating an eccentric bolt at the inside of the rear TTL
    link, which will also change the camber slightly; however, this method should not be used to
    adjust camber because rear toe has a much larger effect on handling and tire wear than rear
    camber.  If the rear camber is out of spec, it should be corrected by fixing any broken parts
    and/or using alternate adjustment methods.

    There are several ways to increase the stock range of camber adjustment:
    CAMBER OR “CRASH” BOLTS: The strut-to-knuckle bolts can be replaced with smaller
    crash bolts, available for ~$3 each from Mazdaspeed Motorsports Development.  Installing
    smaller bolts will increase the clearance in the bolt holes, allowing the steering knuckle to be
    tilted in relation to the strut.  This allows camber adjustment of +/-0.5° if one bolt per side is
    replaced, or +/-1° if both bolts are replaced. 

    This method is cheap but not always reliable because it relies on friction to hold the knuckle in
    place.  If the suspension is subjected to unusually large amounts of force (such as using extra-
    sticky race tires or driving on rough roads), the steering knuckles can shift and knock the car
    out of alignment.  This problem can be reduced by applying paint or glue to the struts right
    before the bolts are tightened.

    SLOTTING THE STRUT-TO-KNUCKLE BOLT HOLES: This method is similar to using
    “crash” bolts, but costs nothing.  However, it is not generally recommended because removing
    material around the bolt holes will reduce the surface area contacted by the strut-to-knuckle
    bolts.  This will reduce friction and make the knuckles even more prone to shifting than when
    crash bolts are used.

    ECCENTRIC STRUT-TO-KNUCKLE BOLTS: These bolts are available from Ingalls
    (http://www.ingallseng.com/) and a variety of other manufacturers.  These bolts allow camber
    adjustment by tilting the steering knuckle, like a crash bolt, but eccentric bolts don’t rely on
    friction so they are more finely adjustable and don’t shift out of alignment as easily.  However,
    they are generally more expensive than crash bolts.  Most “camber kits” available for the
    Protegé from mainstream alignment shops consist of eccentric bolts.

    CAMBER PLATES:  A camber plate replaces the stock upper strut mount with a spherical
    bearing mounted on an adjustable plate, greatly increasing the amount of available camber and
    caster adjustment.  Camber plates also reduce flex at the top of the struts, improving handling.
    They are generally considered to be the best way to add camber adjustment, and are commonly
    found on race cars.  However, they are much more expensive than other methods of adjustment,
    and sometimes require custom fabrication to install. 


What is caster, and how do I adjust it? What are the effects of more or less caster?
    Caster is the angle of car’s steering axis from vertical when viewed from the side.  If the top of the
    steering axis is tilted towards the rear of the car, this is known as positive caster; if it is tilted
    towards the front of the car, this is known as negative caster. Caster can be difficult to visualize
    without pictures. Check the following link:
    http://www.familycar.com/alignment.htm

    The stock camber spec for a BJ Protegé is 0.8°-2.8° positive. More positive caster improves
    straightline tracking and increases steering feel, but also increases steering kickback over bumps,
    and extreme amounts of positive caster will decrease the load on the outside front wheel and
    increase the load on the inside rear wheel of the car during hard cornering, increasing understeer
    (this is generally bad). Caster also has a large effect on the tendency of a car to pull towards one
    side of the road, although the effect is smaller than the effect of camber. A car will pull towards the
    side with more negative (less positive) caster. Caster has virtually no effect on tire wear.

    The important thing to remember when adjusting caster is to keep it the same on both sides of the
    car to avoid steering pull and handling problems. Increasing the positive camber on a Protegé has a
    beneficial effect on steering feel, but too much caster will increase understeer, so you should keep
    the caster within the stock adjustment range.


What is toe, and how do I adjust it? What are the effects of toe-in and toe-out? Will lowering my car
affect the toe?

    Toe is the angle of the tires viewed from above. Toe-in (or positive toe) means that the front of the
    tires are closer together than the rear of the tires; toe-out (negative toe) is the opposite. The stock
    toe spec for the front and rear wheels of a BJ Protegé is –1/16” to +1/4” (-2mm to +6mm, -0.2° to
    +0.6°). Despite the factory specs, toe settings in excess of 1/8” in either direction will generally have
    a very negative effect on tire wear. Toe is adjusted by turning the tie-rod ends. Unless your Protegé
    has broken suspension parts, the stock toe adjustment range is essentially infinite; you will not need
    any additional parts to adjust the toe.

    More front toe-in will increase the car’s tendency to track in a straight line, but will increase tire wear
    on the outside of the tread, make the car’s transitional handling more sluggish and will hurt top speed
    and gas mileage. Front toe-out will make the car’s handling more responsive, but will increase tire
    wear on the inside of the tread and also hurt top speed and gas mileage.

    More rear toe-in will increase the car’s tendency to track in a straight line (the effect is smaller than
    front toe-in), but will increase transitional understeer and have the same effects as front toe on gas
    mileage, top speed and tire wear. Rear toe-out will decrease transitional understeer, but large
    amounts of rear toe-out (more than -1/16” or –2mm) can make the car very tail-happy, especially
    on slippery surfaces.

    Toe adjustment has BY FAR the largest effect on tire wear of any alignment setting. Misadjusted
    toe will kill your tires in a big hurry! Lowering the front suspension of a Protegé will usually increase
    toe-out, and may cause tire wear problems on the inside of the tread. DO NOT MISTAKE
    EXCESSIVE TOE-OUT FOR EXCESSIVE NEGATIVE CAMBER
. Lowering a Protegé
    usually doesn’t increase camber enough to cause a problem. If you lowered you car and your inside
    front tires are wearing out, check the toe first! Do NOT immediately run out and buy a camber kit!


After I replace the struts and/or springs on my Protegé, do I need an alignment? Is there any way to
avoid it?

    An alignment is highly recommended whenever any suspension parts are replaced.  However, if you
    will not be able to align the car immediately after replacing the springs and/or struts, mark the position
    of the top of each strut in the strut tower and put each strut back in the same position when you
    reassemble everything. This will ensure that you don’t radically readjust the camber and caster (see
    above).
