XYZ Racing Super Sport Coilovers — Audi A4 B9 AVANT φ49 (Cancellation Kit for Electronic Damping) 2016-2026

The B9-generation A4 Avant left Ingolstadt with electronically controlled dampers on higher trims, which means swapping to a coilover platform isn’t just a spring-and-strut job – the factory control module needs telling to stop looking for a damper it no longer controls. XYZ Racing’s Super Sport kit for the AU22-3-C chassis includes the cancellation harness that does exactly that, clearing the fault codes and handing full manual control back to the driver.

Fast-road and weekend track use is the brief here, and the Avant’s estate proportions make that a slightly different problem to the saloon. More structure over the rear axle means more weight to control through direction changes, and the Super Sport’s 36-way damping adjustment gives you the range to firm up the back end without turning the ride harsh on the motorway leg to the circuit.

What this coilover does for your 2016-2026 Audi A4 B9 Avant

Full ride height adjustment lets you drop the Avant’s stance without the compromises of a fixed-drop spring kit – correcting geometry as you lower it rather than accepting whatever camber and roll-centre change comes for free. The 36-way damping range covers a wide enough spread that the same set of coilovers works as a daily commuter setup and a trackday setup, just at different clicks. On the nose-heavy quattro layout the B9 A4 shares with the rest of the range, stiffening the front damping cuts down the dive and wallow that comes with hard trail-braking, sharpening turn-in without a full geometry overhaul. At the back, the Avant’s extra structure over the rear axle benefits from the same adjustability – you can carry more support for load or passengers without the ride turning wooden on a Tuesday commute. And because the kit is built to eliminate the discomfort that comes with bumps and rough roads, you’re not trading a stiffer setup for a harsher one on the drive there.

About the Super Sport coilover

XYZ Racing designed the Super Sport around eliminating the discomfort that comes with bumps and rough surfaces – the same ridges and patched tarmac that turn a stiffer aftermarket coilover into a punishment on a daily commute. Ride height is adjustable, so you can set the stance independently of spring rate rather than accepting a fixed drop. The headline figure is 36-way damping adjustment, giving enough range to run the car soft for a motorway trip and firm it up for a session on track without changing parts. XYZ positions the Super Sport as suitable for both weekend racing and daily use, which is the point of that adjustment range – one damper, two very different jobs depending on where the dial sits. On the B9 Avant, that range also has to answer for the estate’s added rear structure and this AU22-3-C variant’s electronic-damper cancellation requirement, which is why the kit bundles the cancellation harness rather than selling it separately.

Fitment for the Audi A4 B9 Avant (2016-2026)

This kit is built for the AU22-3-C chassis – the B9-generation Audi A4 Avant, 2016 to 2026 – specifically the electronic-damping cancellation variant for cars that left the factory with adaptive dampers fitted. Confirm your car falls in that build spec before ordering, since the standard (non-cancellation) AU22-3 kit is a different part for cars without factory adaptive damping.
