The amount a wheel leans in or out at the top is called "camber". As the car turns and the body leans the tire can lose traction as it no longer is making full contact with the road. When the top of the wheel leans in toward the center of the car it's called negative camber; typically a necessary set-up for competition or hard driving. Negative camber at the rear can be just as important as the front and stock rear is often at 0º or even positive! The control of rear camber is by the outer bracket for the rear radius arm which is bolted to the rear subframe.
We offer three methods for changing the rear camber; MS69 is a pair of fixed brackets that only require bolting in place to provide an extra 1.5º of negative camber from the original setting.MS70 is for adjustable camber only or MS73, the ultimate option, allows for completely adjustable camber and rear toe-in. This is done by manipulating an eccentric washer on the outer pivot point of the trailing arm pin. Camber is still adjusted with a turn bolt.
