XYZ Racing Tarmac Rally Coilovers — Audi A4 B8 SEDAN (Cancellation Kit for Electronic Damping) 2008-2016

The B8 A4’s front-biased weight distribution and the added complexity of Audi’s Continuous Damping Control system make it an unusual tarmac rally platform – but a capable one when the suspension is properly sorted. Fitting coilovers to a CDC-equipped B8 means negotiating the ECU’s expectations; the cancellation kit bundled here handles that electrically, keeping the dashboard clear while a proper rally setup runs underneath.

On sealed-stage events, the A4’s planted quattro traction is a genuine asset, but the stock adaptive setup trades rapid bump recovery for everyday compliance. The Tarmac Rally coilover corrects that balance, giving the B8 a suspension tune drawn from competitive stage experience rather than motorway comfort calibration.

What this coilover does for your 2008-2016 Audi A4 B8 SEDAN (Cancellation Kit for Electronic Damping)

Replacing the CDC units with the Tarmac Rally kit transforms how the B8’s front axle responds to crest compressions and surface variation at pace. Damping calibrated for uneven tarmac keeps the tyres loaded over rough stage surfaces rather than skipping, preserving the quattro drivetrain’s traction advantage where the stock setup would allow the front end to bounce. The jolt-absorption characteristics developed through XYZ’s actual rally programme carry over directly to the road-built car, producing a setup that handles the compression through a fast chicane or a crested junction without the body upset that even the firmest setting on the factory adaptive dampers tends to permit. The electronic cancellation element eliminates the persistent CDC fault light – the car reads as a standard A4 to the ECU while running a fundamentally different suspension philosophy beneath it.

About the Tarmac Rally coilover

The Tarmac Rally series is XYZ Racing’s sealed-stage kit, built specifically to absorb the irregular surface impacts that closed-road events and poorly-surfaced competitive stages produce. The damper’s internal tune focuses on suppressing body shock across large compressions – the kind that unsettles the front end mid-corner – while maintaining consistent tyre contact across the variable surface conditions stage driving presents. Every setting within this range comes directly from XYZ’s tarmac rally programme; the tune is not a road kit loosely repositioned for stage use, but a reflection of the loads and frequencies that competitive events actually generate. For B8 A4 owners on the CDC specification, the cancellation kit is an integrated part of this fitment – an electrical necessity addressed in the box rather than handed off to the installer.

Fitment for the Audi A4 B8 SEDAN (Cancellation Kit for Electronic Damping) (2008-2016)

This kit is listed under chassis code AU21-C and covers the B8-generation A4 saloon fitted with Audi’s factory electronic adaptive damping from 2008 to 2016. The CDC cancellation kit is a required component of this specific part number – it is not a match for B8 A4 variants without electronic dampers, which carry a separate XYZ SKU. Confirm your car’s suspension specification before ordering.
