No such thing as a rear camber rod?? WTF? Camber is adjusted using the rear lower control arm. Toe is adjusted at the front of the trailing arm. The range of adjustment on a factory rear lower control arm is very small. The bolt moves 1/4 inch tops. This can move camber a couple degrees on a non-lowered car. On a lowered car, the factory adjustment is inadequate. You will often end up with -2 or -3 degrees of rear camber with the bolt turned to full positive. For this reason (and several others) you should replace your rear lower control arms with something aftermarket (tc Kline, Ground Control, etc.) that offers more range of adjustment. These parts are usually just glorified turnbuckles that expand or contract based on the direction you turn them. The most important thing is on the street you should never run more than -1 rear camber on an e46. Even on the track, much more than -1 will decrease tire patch all other things being equal.
