Factory camber adjustment on the rear of the BMW 1 3 Series is limited and often not enough. Use SPC's rear camber arm to get an additional - 3deg of camber on the E90, E91, E92, E93 as well as the E82 E88 models. Simply replace the OE link with SPC's adjustable link and adjust camber to maximize tire wear, get ready for the track, or optimize handling the way you drive your car. Once camber is where you want it, set toe with the OE cam and you are good to go. This arm is equipped with SPC's upgradedxAxis ball joint bushing and an OE style bonded rubber bushing to maintain factory standards for noise, vibration, and harshness. The arms are sold per side, get two kits if you need to adjust both sides of the car. California Residents WARNING
