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

The S3 Sedan 8V’s factory-fit adaptive dampers are the first problem any circuit-focused owner runs into: pull them for fixed-rate coilovers and the DCC control unit still expects a signal that no longer exists. This Circuit Master kit is built with an integrated cancellation kit for electronic damping, so the swap happens without warning lights, limp modes or a wiring workaround bodged in the footwell.

For a quattro-driven, EA888-powered sedan that puts real power down through all four corners, that clean electrical integration matters as much as the spring rates. This is the Circuit Master spec – XYZ Racing’s setup for sustained circuit lap-time work, not a fast-road compromise – built for owners who are already booking track days in their S3 and want the chassis control to match.

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

With 9720 ways of damping adjustment on tap, you can set the front end firm enough to control the S3’s nose-heavy weight transfer under trail-braking into a hairpin, then back the rear off separately to keep the quattro system putting power down cleanly out of the corner. The 55mm strut body and the kit’s modified rear-integrated design work with the S3’s multi-link rear rather than fighting it, so mid-corner load stays predictable through consecutive laps instead of drifting session to session. Lower, adjustable ride height brings the centre of gravity down for a chassis that’s carrying meaningful turbocharged power and AWD hardware weight, cutting the roll that otherwise eats into corner-exit traction. Because the electronic damping cancellation is handled at the kit level, none of that adjustability comes at the cost of the S3’s factory driver-assist wiring.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s coilover range, developed and run by XYZ’s own racing teams on international circuits before it reaches a road car. Each corner carries three separate adjustment knobs feeding into a combined total of 9720 damping combinations, giving a far finer window for tuning compression and rebound independently than a single-knob unit allows. That precision comes from a small-oil-hole internal design in the damper – on rough tarmac or kerbing you may hear a faint noise as oil passes through the restricted passage, which is a normal characteristic of this construction rather than a fault. The trade-off is deliberate: this damper is tuned for sustained, repeated circuit use rather than daily-drive comfort, so the internals prioritise consistency over multiple hot laps instead of a plush ride. For the Audi S3 Sedan specifically, that circuit-first tuning is paired with the electronic damping cancellation kit so the whole package drops in as a coherent system.

Fitment for the Audi S3 (2013-2020)

Built specifically for the Audi S3 Sedan 8V φ55 platform, chassis code AU54-C, covering the 2013 to 2020 model years. This version includes both the modified rear-integrated suspension design and the cancellation kit for electronic damping, meaning it’s the correct spec for cars that left the factory with adaptive DCC dampers rather than passive suspension. Confirm your S3 Sedan sits within this year range and originally carried electronic damping before ordering.
