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

Rally-spec suspension for a quattro platform like the Audi S3 8V has to solve a problem that a standard coilover never faces: a rear end that has been cut, seamed and reinforced to carry loads the original chassis was never drawn for. This Pro Rally build is the version that ties into that modified rear structure directly, rather than assuming a factory mounting point is still there to bolt to, and it pairs that with a kit that removes the S3’s electronic damper control from the circuit entirely.

For gravel and snow-stage running in a turbocharged, all-wheel-drive S3 saloon, that second part is the one owners underestimate. Once the standard electronic damping is cancelled out, the Pro Rally dampers are running exactly what the driver sets, stage after stage, with nothing in the factory ECU quietly overriding the compression side mid-corner.

What this coilover does for your 2013-2020 Audi S3 Sedan 8V

With the rear structure properly integrated rather than adapted, the S3’s quattro rear end stays located under the kind of hard yaw and compression loading that gravel and snow stages throw at it, instead of working against mounting points designed for a road car. Ride height is adjustable independently of the damper setting, so front and rear stance can be set for stage clearance and weight transfer without touching the compression and rebound tune underneath it. Cancelling the electronic damper control also means the suspension behaves the same on lap one as it does on the last stage of the day, because there’s no factory adaptive system trying to soften or firm the ride based on inputs the driver didn’t choose. On a car that’s already carrying quattro’s all-wheel-drive weight low and rearward, that consistency is what lets a driver actually trust where the back end is going to sit mid-corner.

About the Pro Rally coilover

XYZ Racing draws a hard line between two kinds of gravel and snow suspension, and it’s worth understanding which side of that line this kit sits on. One type bolts straight onto the original chassis as supplied – a more amateur-level setup that asks the standard structure to absorb rally-grade impacts it was never built for. The other, the type used here, is built to go in after the car’s body has already been modified specifically for competition use, with the suspension’s mounting and geometry designed around that reinforced structure rather than around the factory one. That’s the professional-grade approach, and it’s why this particular S3 kit is specified as the "Modified Rr Integrated" version – the rear end it’s designed for has already had the reinforcement work done. Add the cancellation kit for the S3’s electronic damping, and the whole rear assembly is running purely on the mechanical settings the Pro Rally dampers are given, with no factory electronics in the loop.

Fitment for the Audi S3 Sedan (2013-2020)

This kit is built for the Audi S3 Sedan 8V, chassis code AU54-C, across the 2013 to 2020 production run. It is specifically for the Φ55 "Modified Rr Integrated" rear configuration, meaning the car’s rear structure has been prepared for competition-spec mounting rather than left in standard road trim, and it includes the cancellation kit required to take the S3’s electronic damper control out of the equation. Confirm both the modified-rear specification and the electronic damping cancellation requirement against your car before ordering.
