BMW's X5 is notorious for running negative camber and wearing tires. Use this adjustable rear upper control arm to change camber from -1 to +3 degrees on the right hand suspension. Featuring a bonded rubber bushing and a booted adjustable ball joint, this forged aluminum arm will let you set camber to where you want it while maintaining factory ride quality and noise vibration & harshness (NVH). This arm is for the right hand side. Use SPC part #72117 on the left side or #72115 to do both sides.
