XYZ Racing Tarmac Rally Coilovers — Audi S3 SPORTBACK 8V φ55 (Modified Rear Integrated) 2013-2020

The S3 Sportback 8V’s Haldex quattro system will send drive to all four corners the instant the fronts start to slip, but that traction advantage only holds on a sealed tarmac stage if the chassis stays flat over compressions, crests and mid-corner surface changes. XYZ Racing’s Tarmac Rally coilover kit is built around that specific problem: keep the car composed when the road surface stops behaving like a road.

On the AU52 chassis this kit runs the modified rear integrated damper configuration, combining spring and shock into a single rear unit in place of the factory’s separated layout. That matters on a Sportback running quattro, where rear-axle behaviour under transition load is as much a part of the stage pace as front-end grip.

What this coilover does for your 2013-2020 Audi S3 Sportback

Stage roads are rarely flat, and the S3 Sportback’s factory suspension wasn’t set up to absorb repeated big hits without upsetting the car’s line. This kit is calibrated to soak up that impact rather than transmit it straight into the chassis, which keeps the tyre in contact with the surface instead of skipping across it after a compression or a crest. Suppressing that shock body movement is what actually puts the S3’s quattro traction to use mid-stage rather than losing it the moment the surface turns rough. The integrated rear damper unit on this AU52-specific build keeps that control consistent front to rear, so the car settles the same way over a rutted braking zone as it does through a fast, rough sweeper. The result is a chassis that holds its line on tarmac stages instead of skating over the imperfections in it.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally line is set up specifically for sealed-stage rally work rather than smooth-circuit lapping, and the damping is tuned around absorbing the impact of uneven, patched and cambered public-road surfaces rather than a groomed track. The valving is built to soak up a hard hit across a big compression without the shock body kicking back into the chassis, which is the failure mode that costs a rally car time and confidence on repeated stage passes. That control is aimed directly at tyre contact: keeping the tyre loaded and tracking the surface increases the traction you can actually use out of a corner, rather than traction the spec sheet promises. The height-adjustable coilover construction lets the car be set up for a specific stage’s ride height and corner balance rather than one fixed factory compromise. XYZ has carried its settings across from its own Tarmac Rally programme, so the base tune reflects damping decisions made from actual stage running rather than a bench estimate.

Fitment for the Audi S3 Sportback (2013-2020)

This kit is built for the Audi S3 Sportback on the AU52 chassis, covering the 2013 to 2020 production run, and is specified for the modified rear integrated damper configuration rather than the factory’s separated rear spring-and-shock setup. Confirm your car uses this rear configuration before ordering, as the integrated rear unit is not interchangeable with the standard separated layout.
