SPC Performance 09-17 Audi A4/RS4/S4 / 09-16 Audi A5/S5 Front Upper Multi Link Control Arm - Left

When you're looking to dial in your Audi's alignment, especially after lowering it or if you're chasing a specific feel, adjustable control arms are the way to go. This kit from SPC Performance gives you the ability to fine-tune your front camber and caster settings by up to 1.5 degrees. It includes both the left-hand side upper control arms, designed to replace the factory units on Audi B8 and C7 platforms, as well as the Porsche Macan. These arms are built from forged 6061-T6 aluminum, which means they're strong without adding unnecessary weight to your suspension.

SPC uses OE-style booted ball joints and bonded rubber bushings. This is a smart choice because it helps maintain the factory ride quality and keeps noise, vibration, and harshness (NVH) in check, so you don't sacrifice comfort for adjustability. The arms feature large 18mm threaded adjuster links for easy adjustments and come with replacement pinch bolts to make installation straightforward. While Audi doesn't publish a specific caster specification for these multi-link suspensions, SPC recommends aiming for 5 to 6 degrees of caster for better tracking and steering return.
