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

Audi’s factory adaptive damping on the B8 A5 Convertible is calibrated around refinement and motorway composure – qualities that work directly against what tarmac stage driving asks of the chassis. Replacing that system with coilovers built from rally experience requires bypassing the electronic control unit entirely, and that’s exactly what this package is designed to do. The Tarmac Rally coilovers arrive with the cancellation kit included, removing the electrical conflict that would otherwise force mismatched damping profiles between the aftermarket units and the factory ECU.

The open cabriolet body adds a dynamic the coupe doesn’t share. Without the fixed roof structure, the B8’s torsional flex is more pronounced under hard cornering loads, and the suspension has to work harder to keep the car settled across cambered stages and compressions. Quattro adds traction but also weight at the front axle – a consideration when setting up for consistent turn-in through pace notes.

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

Tarmac stages reward cars that can absorb surface variation without losing grip, and the Tarmac Rally coilover is built to that brief. The damper is tuned to handle the impact of uneven pavement and to absorb the jolt from sharp compressions – keeping the tyre in contact with the road rather than bouncing off it. Consistent tyre contact on a cambered stage surface directly translates to lateral grip through corners, and through the B8’s quattro drivetrain, that grip manifests as stable four-wheel traction rather than scrambled wheelspin. Vehicle stability across mid-stage crests, where the A5’s front-biased weight distribution can unsettle a softer-sprung setup, is measurably improved.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s competition-specification coilover line for sealed-surface stage work – not a repurposed fast-road kit dressed up with a different name. Every setting in the damper range was drawn from active tarmac rally racing experience, producing a unit calibrated to absorb what stage roads actually deliver: adverse camber, compressions, patchy surfaces, and the repeated impacts that would fatigue a comfort-biased damper far sooner. Construction prioritises shock body control to suppress unwanted chassis movement at speed, while the valving is calibrated to maximise tyre traction across surfaces that resist easy classification. For B8 A5 Convertible owners taking the car onto closed stages, this is a specification built around those demands from the outset.

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

This kit fits the Audi A5 B8 Convertible quattro (chassis code AU26-C) across the full 2009-2016 production span. The package includes the cancellation kit required for vehicles equipped with the factory electronic adaptive damping system – fitting without it would leave the ECU in conflict with the aftermarket units. Confirm your car’s original damping specification before ordering.
