SPC Performance Audi B9 Front Upper Control Arm Set Left & Right Pair

SPC Performance is known for making suspension components that let you fine-tune your vehicle's alignment. This set of adjustable front upper control arms is specifically made for the Audi B9 platform, including models like the A4, A5, S4, and S5. If you're looking to dial in your front-end alignment beyond factory specs, these arms are a solid choice. They allow you to adjust both front camber and caster by up to 1.5 degrees, which can make a notable difference in how your car handles, especially during spirited driving or after lowering your vehicle.

These control arms are built from forged 6061-T6 aluminum, making them strong yet lightweight. SPC uses OE-style booted ball joints and bonded rubber bushings, which are designed to keep the factory ride quality and minimize noise, vibration, and harshness (NVH). This means you can get improved alignment capabilities without sacrificing the comfortable ride you expect from your Audi. The arms feature large 18mm threaded adjuster links for easy on-car adjustments, and they come with replacement pinch bolts to ensure a secure installation. SPC also recommends aiming for 5 to 6 degrees of caster for better steering return-to-center and tracking on these multi-link suspension cars.

This kit includes both the left and right upper control arms, so you get everything needed to adjust both sides of your Audi B9. When installing, it's always a good idea to refer to the manufacturer's instructions for the precise adjustment procedure and torque specifications. After installation, a professional alignment is essential to set your camber and caster angles correctly.
