XYZ Racing Racing Spec Coilovers — Audi A8L 4WD (OE FOR AIR STRUT) (Cancellation Kit for Electronic Damping) 2010-2017

The D4 A8L is a two-tonne luxury limousine that left the factory on adaptive air struts, and that single fact dictates everything about how you turn one into a circuit car. Strip the air system, kill the electronic damping module, and you have a long-wheelbase quattro saloon with a heavily front-biased mass and a chassis that wants a damper built for actual race conditions, not boulevard ride comfort. That is exactly what this kit is.

The XYZ Racing Racing Spec coilover for the 2010-2017 Audi A8L 4WD is the serious end of the catalogue – a circuit damper paired with a cancellation kit for the OE air strut and the electronic damping ECU. It is aimed at owners running this chassis on track or in time-attack, where the standard adaptive setup simply cannot be valved hard enough to control the weight transfer this car generates under braking and turn-in.

What this coilover does for your 2010-2017 Audi A8L 4WD

The first thing you notice is the body. A long-wheelbase A8L on air pitches and squats in a way that masks what the front axle is actually doing; on a fixed Racing Spec damper that information comes back. Mid-corner balance becomes legible, the nose stops washing as you load the front tyres, and trail-braking turns into something you can lean on rather than something the car argues with. The cancellation kit removes the OE ride-height and damping faults the car would otherwise throw the moment you delete the air struts, so the dash stays clean and the rest of the chassis electronics carry on as normal. Spring rates and damper valving have the headroom for slick tyres and aero loads, which the OE air setup never had.

About the Racing Spec coilover

Racing Spec is XYZ Racing’s circuit-only damper, valved using data collected from direct participation in race series including WTCC. The construction and shim stacks are built for sustained high-load work – repeated heavy braking zones, kerb strikes, and the kind of damper duty cycle that pulps a road-tuned coilover inside a season. Adjustment is on the firmer side of the range because the platform assumes you are running track-appropriate spring rates and tyres. For cars with significant further upgrades – aggressive aero, big slicks, A-class race spec – XYZ Racing will build custom valving against the upgrade list and the specific circuit you intend to run, so the damper that arrives is matched to your build rather than a generic catalogue tune. The supplied cancellation kit is the part that makes any of this possible on a D4 A8L: it electrically replaces the factory air and adaptive damping hardware so the car accepts a conventional coilover without throwing faults.

Fitment for the Audi A8L 4WD (2010-2017)

This kit fits the D4 long-wheelbase A8L quattro, chassis reference AU49-C, model years 2010 through 2017, in OE-air-strut configuration. The package includes the cancellation kit for the electronic damping module, so cars originally fitted with adaptive air suspension can be converted to conventional coilovers without leaving the chassis electronics in an error state.
