Obtaining proper static alignment in your Mustang can be a challenge even on a stock car, as some Mustangs have too much negative camber at stock ride height (see illustration below). Excessive negative camber causes increased wear on the inside edges of your front tires. When you lower your Mustang, the camber becomes more negative. Once the car is lowered, the factory camber adjustment slots may not provide enough range of motion for reducing negative camber to a point where your tires will wear evenly. The MM Caster/Camber plates will provide the ability to set the camber to stock specifications regardless of ride height. They also provide a means of adjusting caster in order to accommodate individual vehicle irregularities.

  Achieving high performance handling requires alignment settings different from the factory specifications. High performance settings would be more negative camber and more positive caster. More negative camber and more positive caster will help keep the tire more upright during cornering, thereby maximizing the size of the tire footprint on the ground. When cornering, body roll causes an increase in positive camber, which pulls up the inside edge of the front outside tire, reducing the effective size of the tire’s footprint. More static negative camber counters this effect. For example, if you have 1 degree of static negative camber, and the camber moves 3 degrees due to body roll, you end up with 2 degrees of dynamic positive camber. If you have 3 degrees of static negative camber, you’ll end up with 0 degrees of dynamic camber – resulting in a larger tire footprint. Due to the steering geometry in the front of the Mustang, just turning the steering wheel will cause the camber of the outside front tire to change, becoming more positive. This effect can be countered by increasing the amount of caster. Enough positive caster (around 4 degrees in a Mustang) will cause the camber of the outside front tire to become more negative while cornering.
