XYZ Racing Pro Rally Coilovers — BMW 3 SERIES G21 (2WD/4WD) 4/6 CYL (Cancellation Kit for Electronic Damping) 2018-2026

The G21 Touring’s factory electronic dampers are tuned for a motorway commute, not for a rutted gravel stage or a snow-packed forest road taken at pace. This cancellation-kit version of the XYZ Racing Pro Rally coilover removes that layer completely: the car’s adaptive damping electronics are bypassed, so the suspension responds purely to the mechanical valving fitted underneath. That is the starting point any rally-spec BMW needs before anything else is set up.

Built for top-flight rally competition, this kit covers the 3 Series G21 across both 2WD and 4WD (xDrive) drivetrains and the full 4-cylinder and 6-cylinder engine range fitted to this generation. Whether the car is running as a lighter 2WD stage machine or the heavier, torque-heavy 4WD xDrive estate, the coilover is specced to cope with the load the G21’s Touring body and boot-mounted equipment add over the rear axle.

What this coilover brings to your 2018-2026 BMW 3 Series

Rally use puts the G21’s suspension through repeated, uncontrolled compressions that a road-biased spring and adaptive damper were never designed to absorb – kerbs, ruts, mid-corner compressions on loose surfaces, and landings after a jump on a forest special stage. Deleting the electronic damping control and running fixed mechanical valving means the response is consistent regardless of surface grip, rather than a computer trying to guess the right damping curve for gravel one moment and tarmac the next. Ride height is adjustable, which matters on the G21 given the extra ground clearance a rally build typically needs over the standard car’s low factory stance. For the 4WD xDrive cars in particular, control over how the rear end settles under power out of a slow corner has a direct effect on how the drivetrain puts power down on loose surfaces.

About the Pro Rally coilover

XYZ Racing builds its rally-spec gravel and snow suspension in two distinct configurations, and this Pro Rally kit sits at the serious end of that split. The simpler configuration bolts straight to the original chassis mounting points, which suits a car still running close to its factory body structure. The second, more involved configuration is built for cars where the body has already been modified for competition – reinforced mounting points, altered geometry, or a stripped-out shell – and the coilover is specified to work with those changes rather than around them. Either way, this is suspension aimed squarely at competition use on loose surfaces rather than a fast-road compromise, with valving and spring rates chosen for repeated hard impacts rather than daily-driver comfort.

Fitment for the BMW 3 Series G21 (2018-2026)

This kit is mapped to the BMW 3 Series G21 (chassis code BM108-C) across the 2018 to 2026 production run, covering both 2WD and 4WD variants and the 4-cylinder and 6-cylinder engine options fitted to the G21 range. The cancellation-kit specification is required on any G21 built with factory electronic adaptive damping, since the standard coilover cannot be run alongside that system.
