XYZ Racing Street Advanced Coilovers — Audi A4 B9 AVANT φ53 (Cancellation Kit for Electronic Damping) 2016-2026

Audi’s B9 A4 Avant left the factory with switchable electronic dampers on DCC-equipped cars, and stepping up to a manual coilover means dealing with a control unit that still expects to talk to a damper it no longer has. This Street Advanced kit for the AU22-2-C chassis includes the cancellation kit needed to retire that electronic damping circuit properly, so the swap doesn’t leave a warning light on the dash.

Street Advanced is XYZ Racing’s road-and-track-day spec – full coilover adjustment for owners who still cover daily miles in the car. On a quattro Avant that already carries extra mass over the rear axle, that’s the right balance: enough control to sharpen the chassis without turning the school run into a chore.

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

Height and camber adjustment let you correct the B9 Avant’s factory ride height, which sits high enough on standard air or DCC suspension to blur the quattro platform’s actual handling balance. With 720 damping settings to work through, you can back off compression for the wagon’s extra unsprung load on rough B-roads, then firm up rebound control when the car is loaded for a track day, so the rear axle doesn’t feel like it’s still catching up with the front. Independent height adjustment also corrects the nose-down stance many B9 Avants develop as their factory dampers age, putting weight distribution back where Audi’s quattro engineers intended it. Because the cancellation kit removes the DCC control loop entirely, there’s no fighting between the factory ECU and the new dampers: what you set on the coilover is what the car actually does.

About the Street Advanced coilover

Street Advanced is the volume model in XYZ Racing’s coilover line, developed over several seasons and validated in competition by XYZ’s own racing teams at circuits around the world. The core spec is 720 damping combinations, split across compression and rebound, giving a finer window of adjustment than a basic two-way unit – useful on a car like the B9 A4 Avant that needs to switch between motorway comfort and a track-day setup without swapping parts. Construction follows XYZ’s standard coilover format for this range: a threaded body for ride height and an adjustable damper carrying the full 720-way range, built for regular road use as much as occasional circuit days. It’s aimed at Audi owners who want real control over how the car behaves, not just a lowered stance, the kind of driver chasing pace who also wants to place the car exactly where they want it, corner to corner.
