XYZ Racing Tarmac Rally Coilovers — Audi A5 B8 COUPE (Cancellation Kit for Electronic Damping) 2007-2016

The B8 A5’s Magnetic Ride system is an impressive piece of road car engineering – variable damping across the full speed range, responding to body movement and road inputs in milliseconds. On a tarmac stage, that variability is a liability. Competition suspension tuning only works when the damper behaves consistently, and Audi’s electronic control loop prevents that entirely. The Tarmac Rally coilover package addresses this at source: the cancellation kit removes the electronic damping system and replaces it with a fixed-force passive setup the car can actually be calibrated around.

For a B8 quattro A5 Coupe on sealed stages, the starting point is reasonable – permanent four-wheel drive, a stiff coupe shell, and a platform with genuine compliance in reserve. The XYZ Racing Tarmac Rally coilover is built to develop that potential, with damper settings drawn from active tarmac rally competition rather than adapted from a road or circuit application.

What this coilover does for your 2007-2016 Audi A5 B8 COUPE

Deleting the electronic damping loop and fitting a fixed-force coilover gives the B8 A5 a suspension system that responds predictably to setup changes: spring rate, ride height, and damper force can be set and repeated knowing the car will behave the same way from one run to the next. The damping targets the sharp compressions that patchy competition tarmac produces – the kind that unsettle tyre contact and push the nose offline mid-corner. Body movement under hard quattro traction loads is also controlled, suppressing the secondary oscillation that bleeds grip when the surface changes character. The combined result is stronger tyre traction and more stable vehicle behaviour through the sequences where the A5 Coupe’s mass and four-wheel drive are being worked hardest.

About the Tarmac Rally coilover

XYZ Racing developed the Tarmac Rally series specifically for sealed-stage competition, with damper calibration drawn from their own rally programme rather than re-tuned from a road or track product. The core engineering focus is impact absorption: handling the abrupt loading of uneven competition tarmac, managing the jolt transmitted through the wheel on a large compression, and controlling the shock body movement that follows. Suppressing that secondary oscillation is what keeps the tyre loaded after the initial hit – on a tarmac stage with high grip levels, small contact patch losses cost measurable time. For B8 A5 Coupe fitments equipped with Audi’s adaptive damper system, the cancellation hardware is supplied as part of this kit; it replaces the original electronic components and is required for the coilover to function correctly.

Fitment for the Audi A5 B8 COUPE (2007-2016)

This Tarmac Rally kit covers the Audi A5 B8 Coupe (chassis reference AU23-C) from 2007 to 2016. The electronic damping cancellation kit is included – confirm before ordering whether your A5 carries Magnetic Ride or another factory active damper system, as this specific fitment is configured for those cars. A5 Coupes without electronic adaptive damping are covered under a separate fitment.
