XYZ Racing Street Advanced Coilovers — Audi S4 B8 4WD (Cancellation Kit for Electronic Damping) 2008-2016

The B8 S4 carries its supercharged 3.0 TFSI ahead of the front axle, and that forward mass is the single biggest thing any suspension setup has to manage on this car. The XYZ Racing Street Advanced coilover for the Audi S4 B8 4WD tackles it directly, replacing the soft factory travel with ride height and damping you set yourself.

This kit is built for the owner who drives hard on the road with the odd track day, not for an outright competition car. It ships as the cancellation-kit version for cars fitted with Audi’s electronic damping, so pulling the adaptive struts will not leave a suspension warning glowing on the dash.

What this coilover kit does for your 2008-2016 Audi S4 B8

Dropping the ride height pulls the S4’s centre of gravity down and closes the gap in the arches, but the real gain is body control. With 720 ways of damping adjustment you can run the car supple enough to survive broken UK B-roads, then wind in more compression and rebound for a circuit session without ever touching the springs. Turn-in sharpens once the front is no longer leaning on its bump stops, and the quattro driveline can put power down earlier on corner exit with the rear settled. On a nose-heavy platform that understeers from the factory, biasing the balance through damping is the difference between fighting the nose and trusting it.

About the Street Advanced coilover

XYZ developed the Street Advanced over several years as its core road-and-track product, refining it through international race use before it reached production. The defining feature is its 720-way damping adjustment, a combined range that moves the car from comfort to firm without removing the units from the vehicle. It is engineered for normal road use with the option of track-day duty, which is why XYZ treats it as everyday equipment for drivers who want speed and control rather than a one-dimensional competition coilover. Height is set independently of damping, so you can chase the stance you want and tune the feel separately.

Fitment for the Audi S4 B8 4WD (2008-2016)

This kit fits the quattro B8 S4 built between 2008 and 2016, chassis code AU22-1-C. It is the variant supplied with the electronic damping cancellation kit, so it suits cars originally optioned with Audi’s adaptive dampers as well as those on passive struts. Check your build year against the range before ordering.
