XYZ Racing Tarmac Rally Coilovers — Audi S3 SEDAN 8V φ55 (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2013-2020

The S3 Sedan 8V’s quattro layout puts noticeably more weight over the front axle than the standard A3, and on a rough tarmac stage that mass transfers hard into the outside front corner under trail-braking. The XYZ Racing Tarmac Rally coilover is built for exactly that load, absorbing repeated compression from cambers, ruts and mid-corner bumps without the front end pitching wide. This φ55-strut kit is specified for the Modified Rr Integrated rear end and includes the cancellation kit needed to remove the factory electronic damping control, so the car runs on fixed mechanical valving instead of Audi’s adaptive system.

Sealed-stage events don’t give you a lap to learn where the surface breaks up – the car has to be predictable from the first corner. XYZ’s Tarmac Rally spec is set up around that demand, prioritising traction off the apex and a consistent ride height under the S3’s quattro power delivery rather than outright track lap times.

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

Swapping the factory electronic damping control for the Tarmac Rally’s mechanical valve stack means the front struts behave the same way every time you hit a given bump, rut or camber change – there’s no adaptive system re-reading the road and adjusting mid-corner. On the S3’s quattro platform that consistency matters most under power out of a hairpin, where torque is already fighting for grip through both axles; keeping the front tyre’s contact patch loaded evenly stops the nose from skating wide as the diff sends drive rearward. Ride height is adjustable independently of the damping, so you can set stance and geometry for a specific stage or road surface without touching the valving underneath it. The φ55 strut body and Modified Rr Integrated rear mounting keep the multi-link geometry within its designed range even at firmer settings, which is where the stock adaptive dampers on this chassis start to run out of adjustment.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s damper for exactly the conditions its name describes: sealed asphalt stages where the surface breaks up, cambers shift without warning and compressions land harder than anything a track kerb throws up. The valving is tuned to soak up the impact of rough, uneven tarmac and to control the jolt through a big hit rather than let it slam through to the chassis – that’s what keeps the tyre pressed into the road instead of skipping across it, and it’s the difference between traction and a moment of wheelspin mid-stage. Controlling that shock through the body also settles the car’s overall stability, which is what lets a driver commit to a line on unfamiliar tarmac with real confidence in how the S3 will react. XYZ built the damping curve from its own Tarmac Rally programme, so the settings reflect what the team found worked over actual stage mileage rather than a bench figure alone.

Fitment for the Audi S3 Sedan (2013-2020)

This kit is specified for the Audi S3 Sedan 8V built between 2013 and 2020, matched to the φ55 strut diameter and the Modified Rr Integrated rear end fitted to this chassis. It includes the cancellation kit required to disable the factory electronic damping control, so it’s the correct spec only for S3 Sedans that left the factory with adaptive dampers – confirm your car’s original equipment before ordering.
