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

This kit gives you a set of four adjustable upper control arms, designed for performance driving on Audi B8 and C7 platforms. You get two arms for each side of the vehicle, allowing you to adjust both camber and caster by up to 1.5 degrees on each side. These arms replace the stock upper links and feature SPC's xAxis sealed flex joints, which swap out the factory's noise-dampening bushings for a more direct, free-pivoting connection. This change makes a notable difference in how the car feels and responds when you're pushing it.

The arms themselves are forged from 6061-T6 aluminum, making them strong without adding much weight. They come with OE-style, maintenance-free ball joints that are booted to keep dirt out. You'll also find large 18mm threaded adjuster links for making those alignment changes, and the kit includes replacement pinch bolts. Because these performance arms use a more direct joint design compared to the original equipment, you will notice more road noise and vibration transmitted into the cabin. This is a trade-off for the improved handling response.

This kit is a solid option if you're looking to fine-tune your suspension for track days or spirited driving. It's important to note that while these arms are designed to fit a range of Audi models like the A4, A5, and Q5, as well as the Porsche Macan, you'll want to confirm fitment for your specific vehicle. For those who might not need the full performance upgrade, SPC also offers versions with OE-style bushings.
