This popular adjustable upper control arm/shim kit has been re-designed to match the SPC family of Nissan and Infiniti arms. Our new tubular design has reduced weight by 1 pound per arm and increased rigidity. SPC's arms are the only 350Z arms on the market that can get +3.5° to -1.5° camber change. Additionally, you will be able to set your caster at ±1°. This patented design makes camber and caster adjustment easy using the sliding and rotating ball joint. The kit includes everything needed, including the ABS sensor bracket, shims, and the adjustable arms
