XYZ Racing Street Advanced Coilovers — Audi A3 8V Φ55 (Rear Twist- beam Suspension) (Cancellation Kit for Electronic Damping) 2012-2020

The 8V A3’s torsion-beam rear axle isn’t going anywhere – Audi kept it on the two- and three-door, front-drive cars to save weight and cost, and it means rear geometry doesn’t move independently the way a multi-link setup does. Every millimetre of control has to come from the spring and damper, not from clever kinematics. XYZ Racing’s Street Advanced coilover is built around that reality, and this Φ55-strut version carries a cancellation kit that lets you delete the factory electronic damping control without the dash throwing up fault codes.

For an 8V running that torsion beam, ride quality lives or dies on damper tuning rather than suspension geometry, and that’s exactly what Street Advanced targets: comfortable enough for the daily commute into work, sharp enough for a track day without a spring change. It’s a road-first, occasional-track spec rather than a dedicated race setup.

What this coilover does for your 2012-2020 Audi A3

Swap out the stock electronically-damped strut and the 8V’s twist-beam rear stops relying on a control module guessing at road inputs – you’re setting the damping yourself, and 720 distinct positions means you’re not stuck choosing between "too soft" and "too firm" with nothing in between. Ride height is fully adjustable too, so you can drop the front-heavy A3 enough to sharpen turn-in without dragging the sump guard over speed bumps. Because the rear beam has no separate camber or toe adjustment, getting the front-to-rear balance right through spring rate and damping becomes the main lever you have for tuning out the A3’s inherent front bias under trail braking. The cancellation kit means the swap is electrically clean – no warning lights, no limp-mode damping defaults fighting your settings.

About the Street Advanced coilover

Street Advanced is the volume model in the XYZ Racing range, refined over several seasons of development and validated in competition by race teams around the world before any of that engineering gets scaled down into a road-biased kit. It’s built for exactly two jobs: everyday road use and the occasional track day, without asking the owner to choose a harsher one-trick-pony setup. The defining number is the 720-position damping adjustment, which is a genuinely fine-grained range rather than a handful of clicks – useful when you’re hunting for the exact compromise between compliance on a B-road and support mid-corner. XYZ pitches it as essential kit for any driver who wants more speed and more control without leaving comfort behind entirely, and that dual brief is what separates Street Advanced from the firmer, track-only tiers in the range.

Fitment for the Audi A3 (2012-2020)

This kit is specified for the Audi A3 8V with the Φ55 strut and twist-beam rear suspension, chassis code AU12-4-4-C, covering 2012 to 2020 production. It includes the cancellation kit required for cars fitted with factory electronic damping control, so the electronic system is neutralised rather than left to conflict with the new dampers.
