XYZ Racing Tarmac Rally Coilovers — Audi A5 B8 SPORTBACK 4WD (Cancellation Kit for Electronic Damping) 2009-2016

The A5 B8 Sportback quattro is an unlikely tarmac stage car on paper – a four-door fastback with a longitudinal engine sitting well forward of the front axle, and a factory suspension system built around electronic adaptive control that was never designed to survive the sustained loading of a sealed stage. In practice, the quattro drivetrain’s traction advantage over a driven-axle competitor more than justifies the weight, and the B8 platform’s structural rigidity is a solid foundation once you remove the OEM damping and replace it with something developed under competitive conditions.

That’s exactly what this XYZ Racing Tarmac Rally coilover kit addresses for the Audi A5 B8 Sportback 4WD. The package includes a cancellation kit for the factory electronic damping system – a necessary step on this chassis variant – and replaces the adaptive hardware with units built from XYZ’s direct tarmac rally stage experience.

What this coilover does for your 2009-2016 Audi A5 B8 Sportback 4WD

Fitting this kit replaces an OEM adaptive system calibrated for road comfort with dampers calibrated specifically for the surface loading of a tarmac stage. Where the B8’s electronic dampers interpolate and adjust, these units respond mechanically and consistently – absorbing large impacts without transferring energy into the body structure. That translates to better tyre contact through rough braking zones and across the surface irregularities that sealed stages invariably produce, which in turn gives the quattro drivetrain a more stable platform from which to deploy its grip out of slow corners. Body movement through fast chicanes and over blind crests is predictable rather than subject to the variable behaviour an overworked adaptive system can introduce when it is being asked to do too much too quickly.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s application-specific kit for sealed-stage competition, and the damper settings it ships with have been developed through direct tarmac rally stage experience rather than derived from road-car or circuit data. The design priority is absorbing the sudden jolt of a large bump or uneven surface patch – suppressing body movement so the tyre maintains contact rather than skipping, and protecting mechanical systems from repeated high-impact loading across a full stage distance. Vehicle stability under those conditions comes from the damper doing its job consistently, not from electronic intervention. The A5 B8 Sportback 4WD version includes all the electronic damping cancellation hardware required for this chassis, replacing the OEM adaptive system cleanly so the B8’s control modules operate without fault codes or further intervention.

Fitment for the Audi A5 B8 Sportback 4WD (2009-2016)

This kit is confirmed for the Audi A5 B8 Sportback 4WD under chassis code AU28-C, covering model years 2009 to 2016 and spanning both the original B8 and the B8.5 mid-cycle facelift. The inclusion of the electronic damping cancellation kit is specific to this build variant – it is required where the factory car left production with electronically controlled adaptive dampers, and cannot be substituted for the non-EDC version of this fitment.
