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

The S1 Sportback 8X’s Haldex-based quattro system sends 228bhp through all four corners, and how that torque splits front-to-rear in the first metre off the line decides whether a launch is clean or just wheelspin and squat. XYZ Racing’s Drag Racing coilover kit for this Audi is built around that exact problem: it changes how much of the car’s static weight sits over the driven wheels the instant you release the clutch.

That’s a different job to a fast-road or circuit coilover. Rather than chasing balanced turn-in or reduced body roll, this Drag Racing setup is calibrated for straight-line launches – getting more of the S1’s weight onto the tyres putting power down, then holding the car settled once it’s moving.

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

Off the line, weight transfer is everything for a quattro hot hatch that’s making more power than its factory suspension was calibrated to handle cleanly. This kit lets you shift static weight rearward and onto the axle doing the launching, so the S1’s tyres compress harder into the tarmac instead of spinning through the first few metres. Less idle wheelspin means more of the 228bhp actually converts to forward motion, which matters more on an AWD car than a straight quarter-mile stopwatch might suggest – the S1’s Haldex coupling only sends torque rearward once it senses front-axle slip, so cutting slip at the source keeps that transfer working the way it’s meant to. Once the car is up to speed, the same settings keep the chassis stable rather than pitching and wandering as it accelerates through the run.

About the Drag Racing coilover

XYZ Racing’s Drag Racing range is built specifically for 0-400 metre runs rather than adapted from a road or circuit platform, and it’s set up to suit FWD, RWD and 4WD cars alike. The core idea is weight distribution: the ride height and spring settings are configured so the car shifts more of its mass onto the driven wheels the instant it’s put under load, rather than sitting in a neutral static stance. That extra compression on the launching tyre reduces the amount of idle wheelspin off the line, which is the main enemy of a consistent 0-400m time on a turbocharged AWD platform like the S1. The same setup carries through into the run itself, holding the car settled at speed instead of letting it move around as traction and aero load change. It’s a single-purpose kit – built for the strip, not for mixing lap sessions with road use.

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

This kit is specced for the Audi S1 Sportback 8X, chassis code AU43-1-C, covering the 2014-2018 production run. It’s the Modified Rr Integrated variant with a cancellation kit for electronic damping included, which disables the S1’s factory electronic damper control so the fixed-rate coilover can run without triggering a fault on the OEM system. Confirm your car has the electronically damped suspension option fitted before ordering this cancellation-kit variant rather than the standard kit.
