SPC Performance Audi and VW Rear Adjustable Control Arm - Left

Forged from 6061-T6 aluminum, these adjustable control arms from SPC Performance are built for strength without adding unnecessary weight. They're designed to replace the front upper control arms on the left-hand side of various Audi and Volkswagen models, including the Audi A6, A8, S6, S8, and the Volkswagen Phaeton. The unique multi-link suspension on these vehicles creates a 'Virtual' SAI, and while the factory doesn't publish a specific caster specification, SPC recommends aiming for 5 to 6 degrees of caster for better tracking and return-to-center feel.

These arms feature OE-style booted ball joints and bonded rubber bushings. This means they maintain the factory ride quality and keep noise, vibration, and harshness (NVH) within expected parameters. The large 18mm threaded adjuster links allow for precise adjustments of both camber and caster by plus or minus 1.5 degrees. This kit includes the necessary replacement pinch bolts for installation. If you need to adjust the right-hand side, you'll want part number 81372.
