What do caster camber plates do for my Mustang?

Written By: Stanley Sadowski

Shop Caster Camber Plates

If you've lowered your Mustang, odds are you are going to need a set of caster camber plates. Save yourself from chewing through a set of tires and make sure you install caster camber plates on your lowered or modified Mustang's suspension.

Mustang caster and camber plates are one of the main parts used in adjusting front end alignment. It's their job to adjust the strut to get optimal placement of the tire.

What Does “Caster and “Camber” Stand For?

Caster is the forward and backward adjustment in the plates. It affects the uppermost point of the steering axis. Caster will not cause uneven tire wear but if not adjusted properly directional control of the steering will be affected.

Camber is the side to side adjustment. This is what changes when the car itself is lowered. Negative camber will angle the top of the tires in towards the center of your Mustang and positive camber point the top of the tires out. Too much negative or positive camber will cause uneven wear of the front tires and premature wear of other suspension parts.

Does my Mustang Need Caster Camber Plates?

In a nutshell, the reasons you might want to consider picking up a set of caster camber plates are as follows:

  • Correct your Mustang's suspension geometry after lowering it
  • Adjustment allows for tire preservation
  • More consistent steering and better steering response
  • They have greater adjustability than the stock plates
  • Dail in your Mustang for a particular track or stretch of road

If you purchased a set of lowering springs then it is extremely important to get a set of aftermarket caster and camber plates. After lowering your Mustang, you will need a front end alignment and this is where your new caster and camber plates will come in handy. Having a properly setup alignment is important for your safety and the performance of your vehicle. It will improve your steering response for cutting corners and keep your car as straight as an arrow on the highway of drag strip. Lowering your Mustang without the use of caster camber plates not only wears your tires and other suspension parts much more quickly, it will negatively affect performance and handling as well.

Does a Stock Mustang Need Caster Camber Plates?

If your Mustang is still in stock form and you are less concerned about performance, you’ll be fine without caster camber plates. However, if you are performance minded or find that your tires are wearing unevenly, a set of caster camber plates should be on your future mod list. While caster camber plates do not directly add power or huge performance differences, they do allow for your current suspension parts to operate the way they were intended to.

What Adjustments Do Caster Camber Plates Make?

The factory caster and camber plates only allow so much adjustment to be made before they are maxed out. Aftermarket plates allow up to twice as much adjustment over factory. Most manufacturers produce a single plate design but companies like Maximum Motorsports and QA1 offer the caster and camber adjustment on separate plates making it a little easier to fine tune the alignment. Either of these designs are a significant improvement over the factory equipment and will be sufficient in dialing in your caster and camber after lowering your Mustang.

Will Caster Camber Plates Fit My Mustang?

Aftermarket caster and camber plates will fit all years 94-04 GT, V6, Mach 1, and Bullitt models but certain products do not pertain to the 03-04 Cobra models. Maximum Motorsports offer different plates for the later Cobras. There are caster and camber plates for all other generations as well.

Caster Camber plates can range in cost from roughly $200-$350, with your higher quality ones being on the higher end of the spectrum. Typically, the price is dictated by the amount of adjustability offered as well as the type of bearings used in the design.

Installing Caster Camber Plates on a Mustang

Installing aftermarket caster and camber plates can be a bit difficult. Some products require you to drill a fourth hole to mount the plates because certain designs use a 4-bolt pattern such as Maximum Motorsports. Although the installation itself is something a DIY enthusiast can handle, the car still must be brought to a shop for a professional alignment.

Other Notable Hardware: If your camber still isn’t where you would like it be then consider picking up some Eibach pro-alignment camber adjustment camber bolts. These bolts install as the top bolt in mounting the strut to the spindle and offer and additional /- 1.75 degrees of camber adjustment.

How To Adjust Mustang Caster Camber Plates

Adjusting the CC plates are as simple as turning screws. However, it can be turning screws several times in order to attain the proper alignment. Proper tools are required in order for proper alignment, without them it is simply a guessing game. Using the tools to attain initial numbers, adjusting the screws to adjust the caster camber to be within stock tolerances (found in the owner's manual) until adjusted properly. Do not forget to check the toe of the wheels as well, which must be adjusted at the tie rod ends and not the plates themselves.
