SPC Performance 17+ Audi A4/S4/ 18+ Audi A5/S5 Front Adj Upper Multi Link Control Arm Kit

This kit from SPC Performance gives you a set of four adjustable upper control arms for the front of your Audi B9 platform vehicle, including models like the A4, S4, A5, and S5. These arms are designed to replace your stock upper links, allowing you to dial in your front-end alignment with adjustments for both camber and caster, each by up to 1.5 degrees. This level of adjustability is crucial if you're looking to optimize your vehicle's handling for spirited driving or track use.

The arms themselves are constructed from forged 6061-T6 aluminum, which means they're strong enough for demanding use while keeping weight to a minimum. SPC has replaced the factory inner bushings with their xAxis sealed flex joints. These joints pivot more freely than the stock rubber bushings, reducing compliance and giving you a more direct feel for what the front tires are doing. You'll also find OE-style, maintenance-free ball joints that are booted to keep dirt out. The large 18mm threaded adjusters make setting your alignment precise and straightforward. Replacement pinch bolts are included to help secure the new arms.

It's important to note that by reducing the compliance of the original bushings, which are designed to absorb noise, vibration, and harshness (NVH), you will likely notice an increase in road noise transmitted into the cabin. This is a common trade-off when upgrading to performance suspension components that prioritize handling response. This kit includes all four arms needed for both sides of your vehicle.
