SPC Performance Audi B9 A4/A5/S4/S5 Front Upper Control Arm Set Left & Right Pair

81383 - AUDI A4 CONTROL ARMS KIT

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. For the left hand (LH) side, use #81381. For the right hand (RH) side, use part number #81382.

SPC Arms Feature:
• Forged 6061-T6 Aluminum construction for maximized strength at a minimum weight
