XYZ Racing Tarmac Rally Coilovers — Audi A6 4G/C7 2WD/4WD 2011-2018

The C7 A6 is an unlikely sealed-stage weapon on paper – an MLB-platform executive saloon whose kerb weight sits well above 1,600kg in its lightest guise – yet on smooth, fast tarmac stages it rewards a driver who understands what the chassis will and won’t do. In 2WD trim that means managing front-axle load under braking and resisting the urge to lean on the steering mid-corner; in quattro spec the weight distribution becomes a traction asset, but the suspension still needs to cope with the compressions and surface changes that define any competitive tarmac stage.

The XYZ Racing Tarmac Rally coilover for the Audi A6 4G/C7 (2011-2018) is built around exactly that brief. Where the standard multi-link setup was calibrated for motorway isolation, this kit is calibrated for the forces that arrive at competition speed.

What this coilover does for your 2011-2018 Audi A6 4G/C7

The C7’s multi-link front and rear geometry means spring rate changes translate predictably to the driver – one of the platform’s genuine strengths for this application. Stiffer springing here doesn’t degrade the car in the way it might on a MacPherson-strut setup; instead, it reduces the body roll that compromises tyre contact across crests and compressions. The damper tune suppresses body shock to keep the tyre loaded against the road surface, which in quattro variants means preserving the grip advantage the drivetrain provides through a wider range of road conditions. In 2WD form, that stability under load makes the A6 feel planted rather than wallowy where the road loses its smoothness between stages.

About the Tarmac Rally coilover

The Tarmac Rally series is XYZ Racing’s application-specific coilover for sealed-stage competition. The calibration is drawn from actual tarmac rally use rather than road-car data, targeting the particular problem of absorbing large surface impacts at speed while maintaining the body control a heavy saloon requires. The damper is designed to absorb the jolt of sudden surface changes – the kind of sharp undulation that would unload a tyre on a standard touring setup – and translate that energy into controlled movement rather than a chassis destabilising kick. Height adjustment allows a competition ride height without sacrificing the stroke needed to handle bigger compressions. Every setting in the kit reflects the knowledge accumulated from running this type of coilover in tarmac rally conditions.
