SPC Performance Audi B9 Upper Control Arm Front Left

If you're looking to fine-tune your Audi B9's front suspension alignment, especially after lowering or for track use, these adjustable upper control arms from SPC Performance are a solid option. They allow you to make precise adjustments to both camber and caster, which are key to dialing in how your car handles corners and how it tracks down the road. This specific part is for the front left side of your vehicle.

These arms are built from forged 6061-T6 aluminum, which means they're strong enough to handle the stresses of performance driving while keeping weight down. SPC uses OE-style booted ball joints and bonded rubber bushings. This is important because it helps maintain the factory ride quality and keeps noise, vibration, and harshness (NVH) within expected levels, so you don't sacrifice comfort for adjustability. The large 18mm threaded adjuster links make it straightforward to dial in your desired alignment settings.

This control arm is designed to fit a wide range of Audi B9 models, including the A4, A5, S4, and S5. It comes with replacement pinch bolts for installation. For the best results, SPC recommends targeting 5 to 6 degrees of caster for improved tracking and steering wheel return-to-center feel.
