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

The B9 A4 Avant carries its weight low and long, with the estate’s extra mass over the rear axle changing how the standard suspension settles under load compared with the saloon. On a car specced with electronic damping from the factory, the Street Advance kit replaces that system outright, giving you a mechanical, driver-set alternative with 720 damping positions to work through rather than a control unit’s own logic.

This is the cancellation-kit variant, built specifically to integrate with a B9 Avant that left the factory with adaptive dampers, so the electronics stand down and the coilover takes over fully. It’s suited to owners who want the estate to hold a line through a fast A-road sweeper without the nose diving into corners, while still being liveable on the motorway commute the extra boot space was bought for.

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

With 720 ways of damping adjustment, you can set the front end firmer to control dive under braking – a trait the Avant feels more than the saloon thanks to the extra weight aft of the rear wheels – and back the rear off enough to keep the axle settled over broken tarmac. Because this kit cancels the OE electronic damping rather than fighting it, there’s no conflict between two systems trying to manage the same corner; you get one damper doing one job, set by you. Ride height is adjustable through the coilover body, so you can drop the estate enough to sharpen turn-in and cut roll without pushing the arches into territory that ruins the load bay’s usable range. Owners running the Avant as a daily will find the breadth of the 720-way range useful precisely because it stretches from a comfort setting for the school run to something noticeably tauter for a B-road blast, without swapping parts.

About the Street Advanced coilover

XYZ’s Street Advance line is the one most B9 owners land on, developed over several seasons of the brand’s own racing programme and refined off what that competition work showed up. It’s built to sit between full daily comfort and track-day stiffness, which is why the 720-position damping range exists – enough granularity to find a setting that suits an Avant carrying passengers and luggage as well as one being driven hard on an empty road. The construction is aimed at drivers who want genuine control over how the car behaves, not just a lower ride height for looks. For a B9 shod with adaptive dampers from new, the cancellation-kit spec is the version that actually fits – it’s engineered to take over the job the OE electronics were doing, not sit alongside them fighting for authority over the same corner.

Fitment for the Audi A4 Model (2016-2026)

This kit is built for the Audi A4 B9 Avant φ49 fitted with the cancellation kit for electronic damping, chassis code AU22-3-C, covering the 2016-2026 production run. Confirm your car left the factory with adaptive/electronic dampers before ordering this variant – the cancellation hardware is specific to that setup and won’t suit a B9 Avant on passive OE suspension.
