Caster/camber plates should be considered an essential item. Once you go through the trouble of modifying your suspension for better performance, the factory adjustments, or lack thereof, are pretty much useless. The Maximum Motorsports setup uses two plates that sandwich a Teflon-lined spherical bearing and several spacers at the top of the shock tower. Once installed, it is evident just how little adjustment you had and how much you have afterward. Follow the directions carefully as the plates are to be oriented in a certain manner; the plate spacers as well as the strut spacers also are specifically located.
