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

The B8 S4’s supercharged 3.0 TFSI sits high and far forward over the front axle, and quattro splits torque rearwards through the centre diff under load – which is exactly the combination that punishes anything short of a proper rally-spec damper on a gravel stage or a broken Tarmac special. Audi’s factory adaptive damping was tuned for the autobahn, not a Welsh forest, and the standard struts collapse into their bumpstops the first time you land a crest with a tank of fuel and a co-driver.

This is the Pro Rally coilover for the S4 B8, supplied with the cancellation harness that defeats the magnetic ride / electronic damping fault codes so the dash stays clean once the OE struts come out. It is built for top-flight rally competition – gravel, snow, mixed-surface stages – not fast road and not circuit.

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

Pro Rally is not a softer version of a circuit damper. It is a long-travel, high-velocity unit designed to keep all four wheels loaded on broken surfaces where a Top Sport or Super Sport would be over-damped and out of stroke. On a B8 chassis that means the nose stays composed over compressions instead of pitching into understeer, and the rear axle keeps biting on corner-exit when the quattro driveline tries to shove torque back to the front. The supplied cancellation kit kills the electronic damping warnings cleanly, so you are not staring at an amber dashboard for the rest of the rally. Expect a heavier, more deliberate ride at road speeds – this is competition kit and it behaves like it.

About the Pro Rally coilover

Pro Rally is offered in two installation philosophies. The amateur-type fitment bolts to the original B8 chassis with no body modification, and is the route most privateer crews take when stepping up from a road-spec coilover. The professional-type fitment is intended to be installed after the bodyshell has been seam-welded, gusseted, or otherwise prepared for rally use – the geometry of the upper mounts and the damper travel suits a car that has already been built for the stages. Both versions share the long-stroke damper body, the rally-grade spring rates, and the high-flow valving that defines the type. This is a competition product first, with the cancellation harness specifically packaged for the B8 S4’s adaptive-damping wiring so the install is clean rather than a wiring hunt.

Fitment for the Audi S4 (2008-2016)

This kit is matched to the B8 S4 quattro on chassis code AU22-1-C, covering the full 2008 to 2016 production run, and ships with the cancellation harness for cars originally specified with electronic damping control. Confirm your car was built within these years and that the magnetic ride / DRC option is present before ordering the cancellation variant.
