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

The B8 S4’s supercharged 3.0 TFSI and quattro driveline make it a fast car in a straight line and a stubborn one sideways. Stock, the chassis is tuned for grip and stability – exactly the traits a drift build needs to unpick. This Drift Spec coilover kit is the suspension half of that conversion, dropping the car onto a platform that rewards steering input rather than fighting it.

It also solves the B8-specific headache: factory electronic damping. The supplied cancellation kit signals out the OE adaptive dampers so the ECU stops throwing fault codes once the XYZ struts are bolted in, which on this chassis is non-negotiable if you want a clean dash and a working ABS module on a competition day.

What this coilover does for your 2008-2016 Audi S4

Drop the ride height into the operating window XYZ designed the kit around and the front axle starts behaving like a drift car instead of a fast saloon. Steering angle increases, weight transfer arrives earlier, and the front tyres bite at initiation rather than washing wide. The damping is set to hold the body still mid-slide, so once you’re committed at angle the car sits planted instead of pogo-ing on bump stops.

On the B8 specifically, the kit lets you run the aggressive static drop these cars need to look and behave the part, while the bump-stroke geometry is set up so you don’t shred the inner arches or run out of suspension travel the first time you clip a kerb. The electronic damping cancellation means no warning lights, no limp mode and no chasing CAN errors at a competition.

About the Drift Spec coilover

The Drift Spec is a single-purpose kit – XYZ Racing builds it specifically for drift competition rather than as a track coilover with a relabelled spring. The geometry, spring rates and damping curves are chosen to stabilise the body during high-speed transitions so the car holds a clean angle through long sweepers and link sections. Lowering brings the roll centre down and tightens initiation response, while the matched bump-stroke prevents the chassis crashing through its travel at full lock.

For an electronically damped B8 like the S4, the kit ships with the cancellation module that retires the factory CDC dampers from the equation, returning full mechanical control of the suspension to the driver. It is a competition-focused product. You can road it, but its character is set up for grip-break and recovery, not motorway refinement.

Fitment for the Audi S4 (2008-2016)

This kit fits the B8-generation S4 with quattro 4WD, chassis code AU22-1-C, covering the 2008 to 2016 model years. The supplied cancellation kit is specific to cars fitted from factory with the electronic adaptive damping option – that’s the variant this part number is intended for.
