SPC Performance Audi A4 / Allroad / A5 / A5 Sportback / S4 / S5 / S5 Sportback B9 Upper Control Arm Front Left

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 two arms to replace the two front upper arms on the left hand (LH) side. For the right hand (RH) side, use part number 81382. Want to be able to adjust both sides? Use part number 81383.

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