The SPC Performance Audi B9 upper control arm (front left) is a forged aluminum adjustable arm that adjusts front camber and caster by +-1.5deg on the Audi B9 platform, with OE style booted ball joints.
Adjust front camber and caster +-1.5deg 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 5deg to 6deg 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.
