XYZ Racing Tarmac Rally Coilovers — Audi A6 4G/C7 2WD/4WD (Cancellation Kit for Electronic Damping) 2011-2018

The C7 A6’s Continuous Damper Control system earns its keep on motorway miles – adaptive, quiet, essentially invisible in normal use. On a tarmac stage, that same system becomes a complication: electronic dampers cannot be removed without the ECU registering faults and disrupting drive select behaviour across the car. This XYZ Racing Tarmac Rally coilover kit resolves that conflict directly, with a bundled cancellation module that satisfies the CDC sensor loop while freeing the chassis from maps written for executive travel.

The calibration behind this kit comes from XYZ’s sealed-stage competition programme. On a car as substantial and as heavy as the C7 – whether the quattro variant managing torque distribution across both axles through a fast stage junction, or the 2WD chassis working against its pronounced front-axle loading – the demands on the dampers are substantially greater than any fast-road context asks for.

What this coilover does for your 2011-2018 Audi A6

The C7’s OEM suspension prioritises isolation over precision, which leaves the car floating through mid-corner compressions and the kind of rough section entries typical of national tarmac stages. This coilover set suppresses that oscillation and keeps tyre contact with the surface – on the quattro, that matters because body movement compounds through the torque-split system into inconsistent axle loading. The 2WD A6 benefits particularly from the traction recovery: once the front axle unloads over a crest, the Tarmac Rally damper’s calibration brings it back into contact faster than the OEM CDC maps allow. Both drivetrain variants gain handling consistency through the damper’s capacity to absorb sharp impacts without transferring the shock load through to the body.

About the Tarmac Rally coilover

The Tarmac Rally series is XYZ Racing’s competition-specification sealed-stage coilover, with all damping characteristics developed from active participation in tarmac rally events – not from laboratory estimates of what stage surfaces might require. The design focus is absorption: specifically, managing the jolt from large surface discontinuities and uneven pavement in a way that preserves tyre traction rather than sacrificing it to body rigidity. Settings across the range come directly from XYZ’s rally racing experience, and the result is a damper that absorbs significant single-hit impacts while continuing to suppress the shock body movement that erodes stability through successive rough sections. For the C7 A6 specifically, the inclusion of the electronic damping cancellation module makes this a complete installation package – the Tarmac Rally coilover is designed from the outset to replace CDC-equipped factory units without generating persistent fault codes.

Fitment for the Audi A6 4G/C7 (2011-2018)

This kit is specified for the Audi A6 on the 4G/C7 platform, chassis reference AU31-C, covering both 2WD and quattro variants across the full 2011-2018 production span. The cancellation module variant is intended specifically for C7s factory-fitted with Audi’s CDC adaptive damping. Cars built without the CDC option require a different specification – confirm your factory options list before ordering.
