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

The B9 A4 Avant’s factory adaptive damping is calibrated for a comfort-and-motorway brief, not a closed-road stage brief. This Tarmac Rally coilover kit is built to override that entirely, and because this fitment includes the cancellation kit for electronic damping, the factory control loop is taken out of the equation and handed over to a fixed mechanical damper that reacts the same way every mile of a stage.

Tarmac Rally is XYZ Racing’s spec for closed-road, sealed-surface competition, where compressions, camber changes and mid-corner crests arrive at speed on a surface far rougher than a racetrack. On the Avant’s estate body, which carries more mass over and behind the rear axle than the A4 saloon, that damper has to control a heavier rear end through the same sequence without the car wandering off line.

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

Swapping the standard adaptive dampers for a fixed mechanical Tarmac Rally set stops the ride height and damping curve shifting under the ECU’s own logic, so what you feel at the wheel is consistent from the first stage to the last. Rebound and compression are set once, mechanically, so the rear of the Avant loads and unloads the same way stage after stage rather than the electronics guessing at a setting for you. Ride height is adjustable independently of spring preload, so you can set stance and road clearance for a given event without touching the spring rate underneath. Because the B9 A4’s engine sits ahead of the front axle line, weight already loads onto the nose under braking; a kit built around this chassis code keeps that front end settled into compressions instead of diving and unsettling the steering. On a rough closed road, that adds up to a car that keeps its contact patches loaded through the sequence rather than just on a smooth apex.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line specifically for closed-road, sealed-surface competition, where the road surface itself is the obstacle rather than a smooth circuit apex. The valving is tuned to soak up the hit from broken tarmac and repeated big compressions without kicking the body around, keeping the chassis settled instead of skipping across the imperfections. That control is aimed directly at keeping the tyre loaded against the road through those hits, because a wheel that’s been thrown off the deck for even a fraction of a second is a wheel with no grip to give. The resulting stability keeps the car pointing where you’ve aimed it rather than needing correction mid-stage. XYZ Racing draws the damping settings on this range from its own Tarmac Rally programme rather than a generic road-car base tune, carried over from stage miles rather than a bench test. On the Avant, that means a coilover already proven at the speed and surface roughness this bodystyle will actually see in closed-road events.

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

This kit is mapped to the Audi A4 B9 Avant, chassis code AU22-2-C, across the 2016 to 2026 production run. It is specifically the cancellation-kit fitment for cars built with the factory electronic damping option, so check whether your car came with that option before ordering – a B9 Avant without it needs the standard, non-cancellation version of this coilover instead.
