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

The B8 A5 Sportback’s factory electronic damping system is competent on road – and a liability in competition. Running a fixed-rate coilover against an active OEM control module generates fault codes and unpredictable damping behaviour; the cancellation kit supplied with this XYZ Racing Tarmac Rally package resolves that conflict at source, delivering a clean, deterministic suspension platform before you leave the service park.

Tarmac rally places specific demands on a car this size. The A5 B8 shares its architecture with the nose-heavy B8 A4, and managing front-axle load through the compressions and high-speed crests of sealed stages is the dominant handling challenge. The Tarmac Rally coilover exists precisely for that environment – events where the surface is sealed but far from smooth, and consistent body control determines whether the car arrives at the following corner correctly pointed.

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

The damping is calibrated to absorb large-displacement inputs – the sudden compressions and blind crests that characterise tarmac stage roads – without sacrificing body control in the corners that follow. Suppressing body movement through impact and returning the car quickly to a stable attitude keeps tyres loaded and in contact with the surface, which directly supports traction and steering accuracy through what comes next. On the A5 B8 with its front-biased weight distribution, maintaining front-axle load across rough sections separates a chassis that steers from one that pushes wide.

About the Tarmac Rally coilover

XYZ Racing drew the Tarmac Rally specification directly from competitive experience on sealed stages, and the damping calibration reflects it. Rather than optimising for the fast, low-amplitude oscillations of a circuit surface, the design targets high-amplitude, lower-frequency inputs – the signature of rally roads – absorbing sudden jolts from uneven pavement and large bumps before they transmit fully through to the body. That body suppression is deliberate: it keeps tyre contact consistent and recovers vehicle stability faster after an impact, converting what would otherwise be a handling interruption into a managed transient. The cancellation kit is packaged with the coilover because the B8 platform’s electronic damping control unit cannot be left active alongside a fixed-rate damper; the kit deletes that electrical loop entirely rather than working around it.

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

This kit covers the Audi A5 B8 Sportback with factory electronic damping across the 2009-2016 model years under chassis code AU27-C. The cancellation kit is a necessity, not an optional extra – the B8 adaptive damping control unit must be bypassed to prevent fault codes and module interference with the fixed-rate damper. Confirm your car carries the adaptive suspension option before ordering; B8 A5 variants built without electronic damping require the standard Tarmac Rally part number.
