XYZ Racing Circuit Master Coilovers — Audi A3 SPORTBACK 8V φ55 (Rear Multi-Link Suspension) Modified Rear Integrated (CancellationKit for Electronic Damping) 2012-2020

Higher-spec A3 Sportback 8V cars left the factory with an electronically controlled damper system, and that control unit has to be satisfied before a fixed-rate mechanical setup can do its job – otherwise you’re fighting the car’s own electronics for control of ride height and damping response. This Circuit Master kit is built specifically for that scenario, pairing a cancellation kit with a fully mechanical, manually adjustable coilover so the multi-link rear end responds only to what you set, lap after session, with no software second-guessing your inputs.

Circuit Master is XYZ Racing’s dedicated circuit setup, built for sustained lap-time work rather than road comfort. On the A3 Sportback’s φ55 rear multi-link geometry, that means a kit sized to keep the rear axle planted and predictable through the transition from trail-braking into mid-corner load, session after session.

What this coilover does for your 2012-2020 Audi A3 Sportback

Once the electronic damping system is cancelled and the mechanical dampers take over, the A3 Sportback’s rear multi-link axle stops hunting for a compromise setting and holds whatever compression and rebound values you dial in. With 9,720 combinations of adjustment split across three external knobs, you can bias the front for turn-in bite on a front-driven or quattro-equipped Sportback and firm the rear to control squat under power out of slow corners – independently, rather than accepting one blended factory curve. The φ55 rear strut diameter adds structural stiffness at the point the multi-link suspension needs it most: under repeated heavy braking into hairpins, where a stock-diameter strut would start to flex and blur your sense of where the rear axle actually is.

About the Circuit Master coilover

Circuit Master is XYZ Racing’s circuit-focused damper line, developed and run by XYZ racing teams across a number of international circuits before it reached retail. The headline figure is 9,720 distinct adjustment combinations, delivered through three external knobs rather than a single dial, giving separate control over compression and rebound characteristics instead of one compromise setting. The valving uses a small-oil-hole design in the damper body; on a rough section of track or a poorly resurfaced patch, that can produce a faint noise as oil passes through the restricted passage, which is a normal characteristic of this design rather than a fault. The kit is built around circuit-surface use, so what would be an occasional annoyance on a broken B-road is simply background noise on a track day.

Fitment for the Audi A3 (2012-2020)

This kit is built for the Audi A3 Sportback 8V, chassis code AU12-8-C, covering the 2012 to 2020 model years fitted with rear multi-link suspension in the φ55 rear strut diameter. It specifically includes the cancellation kit required on cars ordered with factory electronic damping control, so the mechanical Circuit Master dampers operate without interference from the original control module.
