SPC Performance Audi B9 Front Upper Control Arm Set Left & Right Pair

Adjust front camber and caster ±1.5° on the Audi B9 platform with these forged aluminum adjustable control arms from SPC. OE style booted ball joints and bonded rubber bushings maintain factory ride, handling and noise, vibration, & harshness (NVH) parameters. Audi's unique multi-link suspension creates a 'Virtual' SAI. The factory does not publish a specification for caster, but SPC recommends 5° to 6° of caster as a preferred angle for tracking and return to center on these cars. For the left hand (LH) side, use #81381. For the right hand (RH) side, use part number #81382. Want to be able to adjust both sides? Use part #81383.
