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

The S3 Sportback 8V’s optional Audi Magnetic Ride dampers are excellent on the road and largely irrelevant once you start chasing consistent lap times – the electronic control unit is still hunting for a road-biased compromise the circuit doesn’t need. XYZ Racing’s Circuit Master coilover for this chassis is supplied with the cancellation kit built in, so the factory electronic damping control is removed from the loop cleanly instead of left throwing warning lights or defaulting into a limp-mode compromise.

Circuit Master is XYZ Racing’s dedicated circuit-day platform, built for sustained lap-time work rather than a single fast pull on the road. On an all-wheel-drive Sportback carrying its turbocharged four up front, that means damping behaviour that holds its character through session after session, not just the first flying lap before tyres and dampers heat-soak.

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

With the electronic damping cancelled, the Circuit Master’s three external adjustment knobs put damping control directly in your hands, with no software mediating between what the car assumes you want and what the circuit is actually asking for. XYZ Racing’s damper offers 9,720 individual adjustment combinations, which in practice means you can find a setting that keeps the S3 Sportback’s nose planted under trail-braking into slow corners without over-firming the rear and unsettling the quattro system’s torque split mid-corner. Ride height is adjustable independently of that damping curve, so you can lower the car for a reduced centre of gravity without eating into suspension travel over circuit kerbs. The modified rear multi-link integration on the 8V responds well to a firmer, better-controlled damper: expect less squat on power out of hairpins and a rear axle that holds its line rather than wallowing as load shifts off the front under braking.

About the Circuit Master coilover

Circuit Master sits at the top end of XYZ Racing’s damper range, built specifically for competitive track use – closer in spirit to the brand’s Racing Spec and Tarmac Rally builds than to a fast-road daily setup. The design has been proven through XYZ Racing’s own competition teams on circuits internationally, with the adjustment range – 9,720 combinations of compression and rebound – shaped by that testing rather than worked out on paper. The three external knobs meter through a deliberately small oil-hole design, which is what gives the damper its precision toward the extreme ends of the adjustment range; the trade-off is a faint tick from oil moving through those small passages when you catch a sharp ridge or expansion joint. That is a characteristic of the circuit-tuned valving, not a fault, and it is not something you will register at the speeds and on the surfaces this damper is actually built for. Every kit for this fitment is supplied complete with the cancellation kit required to take this S3 Sportback’s factory electronic damping control out of the equation.

Fitment for the Audi S3 Sportback (2013-2020)

This kit is built specifically for the Audi S3 Sportback 8V, chassis code AU52-C, across the 2013-2020 model run, with the modified rear multi-link mounting and Φ55 rear damper specification for this configuration. It is the cancellation-kit variant, so it is the correct choice if your car left the factory with electronic Magnetic Ride damping rather than passive dampers.
