XYZ Racing Pro Rally Coilovers — Audi S1 SPORTBACK 8X (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2014-2018

The Audi S1 Sportback 8X packs a 2.0-litre turbo four and quattro all-wheel drive into one of the shortest wheelbases Audi sells, and on loose surfaces that weight transfers through the suspension faster than in almost anything else built on the A1 platform. XYZ Racing’s Pro Rally coilover exists for that specific brief: repeated, hard compression over broken gravel and washboard stages, where a fixed factory damper simply runs out of range.

This fitment covers the Modified Rr Integrated specification with the cancellation kit for electronic damping – the professional-grade build for cars whose rear end has already been reworked to accept aftermarket geometry, and whose factory electronic damper control needs to be taken out of the loop rather than fooled with a resistor. It’s aimed at the stage rally end of S1 ownership, not fast-road use.

What this coilover does for your 2014-2018 Audi S1

Once fitted, the quattro platform’s tendency to push through the front axle under power out of a hairpin is far easier to manage, because the Pro Rally kit lets you set compression and rebound independently of the ride height needed for rally-spec ground clearance. Full ride-height adjustment protects the underbody on rutted gravel without pushing the car into a soft, wallowing set-up on tarmac links between stages. Because the electronic damping control is cancelled rather than left partially active, there’s no conflict between the factory ECU and the new dampers fighting for authority over wheel control – the mechanical set-up you choose is the one the car actually runs. On snow and loose gravel specifically, where the S1’s quattro system is already sending power to all four corners, a coilover that holds its damping curve through repeated big hits keeps the tyres loaded and the car pointing where you steered it, rather than skating on a compression stroke that’s already used up its travel.

About the Pro Rally coilover

XYZ Racing builds its rally-spec gravel and snow suspension in two distinct forms. The amateur-type kit bolts directly to the original chassis mounting points, aimed at owners running a largely standard body. The professional-type kit – which is what this Modified Rr Integrated, cancellation-kit fitment is – is built for cars that have already had their rear end modified to accept it, and is the specification used on full stage-rally programmes rather than club-level events. That distinction matters because a rally suspension does a job a road or track coilover never faces: absorbing hundreds of full-travel compressions across a single stage, on a surface that changes texture metre to metre, without the internals overheating or the damping characteristic drifting as the stage total climbs. The Pro Rally range is built around that duty cycle rather than around one fast lap.

Fitment for the Audi S1 SPORTBACK 8X (2014-2018)

This kit is specified for the Audi S1 Sportback 8X, chassis code AU43-1-C, covering the 2014 to 2018 production run. It is built to the Modified Rr Integrated standard, meaning the rear suspension mounts are expected to already be reworked to accept it, and it includes the cancellation kit needed to remove the factory electronic damping control from the loop.
