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

For sealed-stage tarmac rally work in the G82 M4, the standard adaptive dampers are tuned around road-going compliance, not repeated compression cycles across changing surface grip between stages. XYZ Racing’s Tarmac Rally coilover kit for the G82 replaces that electronic damping outright, and because the M4’s factory dampers are wired into the car’s stability control, this fitment is supplied with the cancellation kit that lets the electronics run clean once the OE units are gone.

This is the BM118-1-C application, built around the M4’s modified rear-end integration so the coilover mounts to the car’s multi-link rear geometry without fighting the factory subframe bushing points. It’s a rally-specific spec rather than a circuit one – taller usable travel and a damping curve built for the S58-powered M4 hitting compressions at speed on tarmac stages, not a low, flat setup optimised purely for a smooth circuit surface.

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

On a rally-prepped G82, the immediate change is how the car absorbs a stage’s imperfections without the rear end skipping sideways off camber changes or crest compressions. The kit’s damping settings, carried over from XYZ’s own Tarmac Rally programme, are built to control body movement through a hit rather than let the chassis pogo off it, which keeps the rear tyres loaded and gripping instead of unweighting mid-corner. Ride height and spring rate adjustment let you set the M4 up for a specific stage’s surface break-up rather than a compromise setting, and because the cancellation kit removes the factory electronic damper logic entirely, there’s no conflict between the car’s own stability software and a suspension setup it was never calibrated for.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally line is built around one job: controlling a car over broken and uneven tarmac at rally pace, where the surface degrades lap to lap and stage to stage in a way a closed circuit doesn’t. The valving is set to absorb sharp compressions from potholes, patched surfaces and mid-corner ridges without transmitting that impact straight into the chassis, which is what keeps the rear tyres in contact with the road and the car pointed where the driver aimed it rather than deflected off-line. That same control is what XYZ describes as the stability behind "perfect handling" in its own rally programme notes – not outright stiffness, but a damper that settles the body quickly enough that the next input can be trusted. For the G82 M4 that means a kit engineered from XYZ’s own stage-driving experience, translated into ride height and damping adjustment the owner can set for a specific event rather than a single fixed factory curve.

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

This kit is built for the G82 M4, chassis code BM118-1-C, covering the 2021 to 2026 model years with the modified rear-end integration for the car’s multi-link rear geometry. Because the G82 runs factory electronic damping, the cancellation kit is included as part of this fitment so the car’s control units stop looking for a damper signal that no longer exists.
