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

The D4 A8L is the long-wheelbase, aluminium-bodied luxury saloon Audi never intended for stage work – which is precisely why a proper rally conversion is interesting. Strip the adaptive air system off a 4WD A8L and the chassis suddenly has options it never had from the factory: real spring rates, real damping, real ride height control instead of a ride-height sensor and a compressor.

This is the XYZ Racing Pro Rally coilover built for that exact swap. It replaces the OE air strut hardware and includes the cancellation kit needed to silence the electronic damping module, so the dashboard doesn’t throw a fault the moment the car wakes up. It is aimed squarely at top-flight rally competition on gravel and snow, not the school run.

What this coilover does for your 2010-2017 Audi A8L

Pulling the air suspension off a D4 A8L is a bigger change than it sounds. The car loses the soft, floating ride height and gains a fixed mechanical platform that actually loads the tyres predictably when the surface is loose. On gravel, that means the front quattro axle hooks up out of slow corners instead of skating wide on compressed air. On snow, it gives you something honest to brake against.

The Pro Rally hardware is engineered around long-travel gravel and snow work, with damping valved for repeat compression hits rather than smooth tarmac. Combined with the cancellation kit, you also drop the weight and complexity of the OE compressor, reservoir and level sensors – a meaningful reduction on an aluminium car that already lives or dies on chassis balance.

About the Pro Rally coilover

XYZ Racing splits its rally gravel and snow suspension into two configurations, and this Pro Rally kit is the professional version: built to be fitted after the bodyshell has been modified for competition use, not bolted onto an unmolested OE chassis. That distinction matters. The amateur-spec rally kit bolts to the standard chassis and lets a club-level car run loose surfaces; the professional version assumes you have done the seam welding, strut tower bracing and turret work that a real stage car needs.

The construction is biased toward survival on gravel and snow rather than tarmac smoothness – longer usable stroke, damping built to absorb repeated high-energy compressions from jumps and ruts, and serviceable internals because rally cars eat suspension. The cancellation kit for the electronic damping is part of the package, not an afterthought, so the car’s CAN bus accepts the swap cleanly.

Fitment for the Audi A8L (2010-2017)

This kit is specific to the D4-generation Audi A8L in 4WD quattro form, chassis code AU49-C, covering model years 2010 to 2017. It is the OE-for-air-strut variant – meaning it replaces the factory air suspension hardware directly – and ships with the cancellation kit required to disable the electronic damping control on this platform.
