This pair of patent pending adjustable front upper control arms will give +-4deg camber and +-4deg caster change. SPC arms match the OE design for clearance so you can get up to +2deg camber change without fender well interference. If more positive change is needed use the included +2deg camber shims for fixed change and dial in the rest with your arms. The rubber isolated xAxis sealed flex joints retain OE bushing values (Noise, Vibration, and Harshness - NVH), while providing the handling qualities of a mono-ball. Optimized geometry and high strength forged steel components make this the strongest adjustable arm on the market today. Whether you want a cambered stance, improved handling, or to minimize tire wear, this is the best arm for you. US Patent # US 2016/0059652 A1 California Residents WARNING.
