XYZ Racing Tarmac Rally Coilovers — Audi S3 SEDAN 8V φ55 (Cancellation Kit for Electronic Damping) 2013-2020

The Audi S3 Sedan 8V left the factory with electronic adaptive damping wired into its quattro chassis – fine for the commute, a genuine handicap the moment you’re crossing a rutted forest stage or broken tarmac at competition pace. XYZ Racing’s Tarmac Rally coilover strips that system out entirely, and this cancellation kit for electronic damping removes the factory control loop so the car runs on mechanical damping the driver actually sets, not a computer tuned for public roads.

Built around a 55mm (φ55) strut body, this kit is set up for sealed-stage tarmac rally work, where the S3’s quattro platform needs to put power down cleanly out of tight, repeated direction changes without the nose diving into every compression. XYZ Racing’s own rally programme shaped the base valving, so the settings arrive close to where a tarmac-stage car actually wants to sit before you touch a clicker.

What this coilover does for your 2013-2020 Audi S3 Sedan

Cancelling the factory electronic damping stops the two systems arguing with each other – without it, adaptive dampers will fight external coilovers and give inconsistent feedback exactly when you need to trust the car most. With the electronics out of the loop, the 55mm struts respond only to spring rate and the damping you actually set, which matters on the S3’s nose-heavy transverse-engine, quattro-driven layout: turn-in stays predictable instead of shifting between soft and firm settings mid-corner. Ride height adjustment lets you correct the S3’s factory-biased weight distribution for a rally-spec stance, and the stiffer overall control keeps the front axle loaded through compressions instead of ballooning over crests. Traction off the line and out of hairpins improves too, since a chassis that isn’t compressing unevenly under quattro’s power delivery puts that drive to the road more consistently.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line specifically to handle the impact loading of uneven competition surfaces – the repeated, sharp hits a rally stage throws up that a road-biased coilover simply isn’t valved for. The damper absorbs the jolt from bigger compressions rather than transmitting it straight into the chassis, which keeps the body settled and stops the tyre skipping off the road surface on the rebound. That control is aimed squarely at tyre contact: suppressing body shock through a hit increases the traction the tyre can actually generate on the way out of it, rather than losing the contact patch mid-stage. The result is a car that holds its line through a sequence of compressions instead of getting progressively more unsettled as the stage goes on. XYZ Racing’s own tarmac rally programme set the base tune, so the valving reflects what the team has run under stage conditions rather than a generic fast-road compromise.

Fitment for the Audi S3 Sedan (2013-2020)

This kit is built for the Audi S3 Sedan 8V, chassis code AU53-C, across the 2013 to 2020 production run. It’s specified as the cancellation kit for electronic damping, so it’s the correct choice if your car left the factory with adaptive dampers and you need the control electronics removed from the loop rather than left in place alongside the new struts.
