XYZ Racing Street Advanced Coilovers — BMW 4 SERIES G82 M4 (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2021-2026

The G82 M4’s adaptive M suspension ties its factory dampers into the car’s electronics, which is why fitting the XYZ Racing Street Advanced coilover here comes bundled with a cancellation kit – the software layer that watches for OEM damper signals gets switched off, so the twin-turbo S58’s torque and the M4’s near-1,600kg kerb weight are managed through the coilover’s own 720-position damping range rather than fought by a dashboard warning light. The kit also builds in the rear-integrated modification needed to mount a coilover on the G82’s multi-link rear axle.

Street Advanced is XYZ’s road-biased spec, built to hold its composure on a track day without turning the drive home into a chore. On a car carrying this much power through a body heavier than the M3/M4 generations before it, that balance between compliant and controlled matters more than outright stiffness.

What this coilover does for your 2021-2026 BMW 4 Series G82 M4

Fitted to the G82, the 720-way damping adjustment lets you separate low-speed compression for motorway and B-road comfort from the high-speed control the S58’s torque demands under hard acceleration out of a corner. The M4’s nose carries a heavy straight-six and turbo hardware, so front-end support during trail braking is where this kit earns its keep – stiffen the front circuit and the car resists diving into corners under brake, sharpening turn-in without beating up your spine on the way there. At the rear, the multi-link axle, addressed through the rear-integrated modification, gets damping matched to the front so the back of the car stays settled when you get back on the throttle out of slower corners rather than stepping wide. Ride height is also adjustable, which lets you correct the nose-down stance a stiffer spring rate can leave on the factory geometry and keep the arch gaps even front to rear.

About the Street Advanced coilover

XYZ built the Street Advanced range as its core product, developed over several years and refined through the brand’s involvement in motorsport competition around the world. It is pitched as the coilover for owners who want one set-up that works for normal road use and still holds up on a track day, rather than a dedicated circuit-only spec. The defining figure is 720 damping positions, a far finer adjustment window than a basic single-adjustable kit gives you, so you can move from a compliant road setting to a firmer track setting in small, repeatable steps instead of broad jumps. Construction follows XYZ’s usual coilover format – height-adjustable, threaded body, monotube-style damper – matched to the spring rates and valving XYZ specifies for the G82 platform. It is built for drivers who want to feel every change they make to the setup, not just for those chasing a single lap time.

Fitment for the BMW 4 Series G82 M4 (2021-2026)

This kit is built for the G82-generation BMW M4, chassis code BM118-1-C, covering the 2021 to 2026 model years. It includes the rear-integrated modification required to mount a coilover on the G82’s rear multi-link axle, and the cancellation kit needed to remove the factory electronic damping signal so the car doesn’t flag a suspension fault once the OEM dampers are gone. Check your specific G82 M4 build against these details before ordering.
