Does my Fox Body Mustang Need Caster Camber Plates?

Written By: Connor MC

Caster camber plates will dial your front suspension back in after you have installed lowering springs. These plates can be an essential modification if you plan to lower your Mustang.

If you've lowered your Fox, you'll want to consider getting a set of caster camber plates. Here's the science behind them and why your lowered Mustang might need them.

Despite the stock plates being called “adjustable,” they're only marginally so. The lack of camber adjustability rears its ugly head when the car is lowered, be it a result of lowering springs or the stock units wearing such that the car sags. In either of these events, the stock plates do not allow enough adjustability such that there will be too much negative camber, leading to premature tire wear on the inner most edge facing the vehicle.

Furthermore, the stock plates leave zero adjustability for caster, thus making a good front end alignment difficult, if not impossible, to do, especially on lowered Mustangs. The purpose of caster is to keep the tires as vertical as possible through a turn, to better grip and traction. The solution to these woes comes in the form of aftermarket caster camber plates. These are specially designed units to replace the stock strut plates and allow a much larger degree of adjustability for camber and caster tweaking.

Aftermarket Mustang Caster Camber Plates

  • Come as two plates instead of the stock single plate
  • Helps manage shock travel and suspension geometry
  • Compliments other suspension mods
  • Not difficult to install

Aftermarket caster camber plates actually come as a set of two plates that overlap each other, as opposed to the single strut plate used from the factory. Overlaying the individual plates allows you to dial in the exact setting you want, without affecting the other. Additionally, many aftermarket plates feature higher strut mounting, which increases strut travel and prevents bottoming the strut out (good for lowered Foxes), and keeps the strut midway through its travel length for best response.

So to get back to the initial question... should you install aftermarket caster camber plates on your pony? While the idea of caster camber plates isn’t entirely exciting (doesn’t add horsepower, doesn’t shoot flames out of the exhaust, etc.) it certainly is a worthwhile modification. First off, as already discussed, it will correct the geometry problems inherent within the stock front setup. Secondly, it will help later down the road if you wish to further your suspension mods to really squeeze every bit of performance out of the front end.

Brief Note on Caster Camber Install

Install can be done at home with basic tools. In a nutshell, jack the front end up, secure it on jackstands (on the subframes), remove wheel, rotor. Place jack under the control arm (for support), then disconnect the strut. Lower the control arm a bit to get the strut out. Then simply slide off the old strut plates and place the new ones on, in accordance to their manufacturer’s instructions. After that, bolt everything back up and get the ‘Stang a real alignment!
