The Audi S1 Sportback 8X carries its quattro all-wheel-drive hardware and turbocharged four-cylinder ahead of the rear axle, and on a car this compact that means front-heavy weight distribution shapes almost everything about how it turns in and puts power down. XYZ Racing’s Super Sport coilover kit is built around that reality: a fast-road and weekend-track set-up that lets you firm up body control without turning a small, usable hatchback into something that beats you up on the way to the circuit.
Because the S1 splits drive across all four corners, spring and damping choices matter more here than on a front-drive equivalent – get the balance wrong and you either lose the grip advantage quattro gives you out of slow corners, or end up with a ride too stiff for the daily commute. This kit is aimed squarely at owners who want both.
What this coilover does for your 2014-2018 Audi S1 Sportback
Fit the Super Sport kit and the first thing you’ll notice is how much more the S1’s chassis tells you about what the front tyres are doing under braking and trail-in, where the standard set-up leans on soft bushing and generous suspension travel to mask body movement. The 36-way damping adjustment lets you soften the compression side for a lumpy B-road one day and firm the whole car up for a track session the next, without swapping parts. Ride height adjustment brings the centre of gravity down and corrects the slightly high factory stance, which matters on a car that’s already carrying its weight up front. Under quattro power-down out of second- and third-gear corners, tighter body control keeps the rear axle doing its share of the work instead of the front end pushing wide.
About the Super Sport coilover
The Super Sport is XYZ Racing’s damper for owners who won’t accept a trade-off between a comfortable daily drive and a car that holds its composure when driven hard. The core problem it’s built to solve is the harshness that a stiffer aftermarket set-up usually introduces over broken tarmac and speed humps – this kit is tuned to take the edge off that impact without going soft everywhere else. Ride height is adjustable independently of the damping, so you can set the S1 lower for a cleaner stance and better aero balance without also locking yourself into a harsh ride. The 36-way adjustment range covers everything from a settled motorway cruise to a stiffened-up track setting, and XYZ Racing pitch this specifically as a kit that can go from a weekend on circuit back to daily commuting duty without needing to be reset each time.
Fitment for the Audi S1 Sportback (2014-2018)
