These billet aluminum arms fit the 3-Series (E36/E46/E85) along with the new Z4, giving you -1.0 to +3.0 degrees of rear camber change. Great for these popular tuner vehicles, these machined parts are in a stand-out silver anodized finish with SPC "Red"nuts. Our standard EZ Arm (#67110) for BMWs is also available.
