XYZ Racing Tarmac Rally Coilovers — Audi A3 8V Φ55 (Rear Multi-Link Suspension) (Cancellation Kit for Electronic Damping) 2012-2020

The multi-link rear axle on the A3 8V only shows up on the higher-output and quattro-equipped cars, and those same cars are the ones Audi fitted with electronic adaptive dampers as standard. Pulling the factory units for fixed-valve Tarmac Rally dampers means the electronics that used to soften or firm the ride on command are gone, so this kit includes the cancellation loom needed to stop the dash throwing damper-fault warnings once they are.

That matters because sealed-stage tarmac work punishes a chassis differently to a track lap: kerbs, camber changes and mid-corner surface breaks arrive without warning, and a car still running its factory adaptive logic will hunt for a setting instead of just absorbing the hit. The Tarmac Rally spec is built around fixed, driver-set damping instead, so the car behaves the same way on the tenth stage as the first.

What this coilover does for your 2012-2020 Audi A3

On the multi-link rear, spring and damper rates matched specifically to Tarmac Rally use let the axle stay loaded through direction changes rather than skipping over broken surfaces, which keeps the rear tyres working when you need traction out of a hairpin. Up front, the firmer low-speed damping resists the nose-dive that unsettles the A3 under hard braking into a stage junction, so the car stays flatter and turns in predictably straight afterwards. Ride height is adjustable at each corner, so you can set the car for the ground clearance a given stage demands without touching the spring rate. Because the electronic damping is cancelled rather than left fighting the new hardware, the response you get at the wheel is what the dampers are actually doing, not a compromise between two systems.

About the Tarmac Rally coilover

XYZ Racing built this damper specifically around sealed-stage tarmac work, where broken and uneven surfaces are the norm rather than the exception. The valving is tuned to soak up sharp hits from potholes and camber breaks without transmitting the shock straight into the body, which keeps the tyre in contact with the road instead of skipping across it. That contact is the point: more consistent tyre loading means more usable traction on the kind of surface that catches drivers out mid-stage. The result is a car that settles quickly after a hit and holds its line rather than needing constant correction. Every setting in this range comes out of XYZ Racing’s own tarmac rally programme, not a generic road-and-track compromise.

Fitment for the Audi A3 8V Φ55 (Rr Multi-link Suspension) (Cancellation Kit for Electronic Damping) (2012-2020)

Built for the A3 8V chassis code AU12-4-C, covering the 2012 to 2020 production run fitted with the multi-link rear suspension. This variant includes the cancellation kit required for cars specced with factory electronic damping control, so the dash reads correctly once the fixed-rate units are in.
