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

SPC Performance is well-known for making parts that let you dial in your suspension alignment. This front adjustable upper control arm kit is designed for Audi B8 and C7 platforms, including models like the A4, A5, A6, and Q5, as well as the Porsche Macan. If you're looking to fine-tune your vehicle's handling, especially after lowering or installing new suspension components, this kit allows you to adjust both front camber and caster by up to 1.5 degrees. This is crucial for correcting alignment issues and achieving the precise handling characteristics you want.

These arms are built from strong, lightweight forged 6061-T6 aluminum, which helps reduce unsprung weight without sacrificing durability. SPC uses OE-style booted ball joints and bonded rubber bushings. This means you get the adjustability you need while maintaining the factory ride quality, handling feel, and keeping noise, vibration, and harshness (NVH) within expected parameters. The kit includes four arms, enough to replace both upper links on each side of the vehicle, and comes with the necessary pinch bolts for installation. SPC also notes that while Audi's multi-link suspension creates a 'Virtual' SAI, they recommend aiming for 5 to 6 degrees of caster for improved tracking and steering return-to-center on these specific cars.

This kit is a comprehensive solution for dialing in your front-end alignment. It's important to note that while this kit includes the arms and pinch bolts, you'll want to consult your service manual or a qualified alignment technician for the proper adjustment procedures and specifications for your particular vehicle. Replacement ball joint boots are also available separately if needed down the line.
