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

The Audi S1 Sportback 8X pairs quattro all-wheel drive with a compact three-door shell across its 2014-2018 production run, and that combination punishes soft factory dampers the moment you load the front axle into a hairpin. XYZ Racing’s Racing Spec coilover replaces the S1’s standard suspension with a setup built specifically for circuit and time-attack driving, where body control under trail-braking and mid-corner load transfer decide how much of that quattro traction you actually get to use.

This fitment includes XYZ Racing’s cancellation kit for electronic damping, specified for S1s built with the factory’s electronically controlled damper option. Fit it and the car stops looking for a damper control module that no longer exists, so the swap to fixed-rate Racing Spec hardware goes in clean rather than throwing fault codes.

What this coilover does for your 2014-2018 Audi S1 Sportback 8X

On a car this short and this reliant on quattro traction out of slow corners, spring rate and damping quality matter as much as outright grip. The Racing Spec kit cuts the body roll the S1’s standard dampers allow, so weight transfers onto the outside front tyre faster and the driveline has a stable platform to put torque down at corner exit. Ride height is adjustable, which lets you correct the S1’s front-heavy stance and level the car for even contact-patch loading front to rear. Under hard braking into a chicane, reduced dive keeps the nose from diving into the tyre’s working range early, holding front-end grip in reserve for the corner instead of burning it under the brakes. For drivers running the S1 on track days, that adds up to a car that changes direction with less delay between steering input and chassis response.

About the Racing Spec coilover

XYZ Racing’s Racing Spec line is the company’s dedicated circuit-racing damper, and its baseline valving isn’t guesswork: it comes out of XYZ’s own participation in touring car racing, including direct involvement at WTCC level. That background shows up as damping calibrated for sustained high-load cornering rather than a single fast lap, holding its behaviour across a full track session instead of fading after a handful of hot laps. For S1 owners running more aggressive builds – bigger turbos, uprated brakes, or other factory-race-style modifications – XYZ Racing also offers a bespoke route: supply details of the car’s upgrades and the circuit it will run, and the Racing Spec damper can be custom-valved around that specific combination, the same process XYZ uses for full factory racing cars and A-class competition builds. Off the shelf, the standard Racing Spec kit already covers the great majority of track-driven S1s without needing that custom step.

Fitment for the Audi S1 SPORTBACK 8X (Modified Rr Integrated) (Cancellation Kit for Electronic Damping) (2014-2018)

This Racing Spec coilover is built for the Audi S1 Sportback 8X, chassis code AU43-1-C, across the full 2014-2018 production run. It’s specified for cars fitted with the factory’s electronically controlled damper system – the included cancellation kit lets the Racing Spec’s fixed-rate hardware replace those dampers without triggering electronic damping fault codes. Confirm your S1 was built with the electronic damping option before ordering this variant rather than the standard kit.
