SPC Performance Adjustable Front Upper Control Arm Kit for Audi B9 A4/A5/S4/S5

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 a caster, but SPC recommends 5° to 6° of caster as a preferred angle for tracking and return to center on these cars. This kit includes four arms to replace both upper links on both sides of the vehicle.
