XYZ Racing Top Sport Coilovers — BMW X4 G02 4WD (Cancellation Kit for Electronic Damping) 2018-2026

The G02 X4 carries its weight high and its electronics tight, and the factory adaptive dampers spend most of their effort hiding that fact rather than letting the chassis breathe. Strip the electronic damping out and the SAC body has a surprisingly willing platform underneath – longer wheelbase than an X3, a lower roofline, and xDrive that wants to be driven into a corner rather than coddled out of one. The XYZ Racing Top Sport coilover is built for that conversation.

This is the kit for an owner who takes a 2018-2026 X4 G02 to occasional track days and still uses it on the school run on Monday. The supplied cancellation harness shuts down the OE adaptive damping module cleanly so no fault codes light up the cluster, and the Top Sport damper takes over with a 30-coordinate range that finally lets the chassis tell you what it is doing.

What this coilover does for your 2018-2026 Bmw X4 G02 4WD (Cancellation Kit for Electronic Damping)

Ride height drops the X4’s centre of gravity where it most needs to come down – around the front axle, where xDrive’s transfer case and the inline-six sit. With spring rates roughly 2kg/mm firmer than the OE adaptive setup and damping uprated by 30 to 50 percent, the body stops rolling onto the outside front tyre mid-corner, which is where the G02 loses its composure on a quick B-road. The car settles faster between direction changes, the rear axle starts contributing instead of just following, and trail-braking into a long third-gear sweeper turns into something the chassis enjoys. Day to day, the bump absorption is firmer than stock but not punishing – the damper still soaks broken tarmac and motorway expansion joints because the valving was built around real-road compliance, not a bench number.

About the Top Sport coilover

The Top Sport sits in XYZ Racing’s range as the dual-purpose option – the one tuned from the company’s circuit programme but valved back to a setting that survives daily use. Construction is full-length adjustable so ride height changes do not eat into damper stroke, and the damping body uses XYZ’s racing-derived valve stack with 30 clicks of adjustment from soft to firm. Spring rates are matched specifically to the G02 platform rather than carried over from a generic 4-Series catalogue, which matters on a vehicle this tall. The remit is straightforward: 30 to 50 percent more damping force than a street coilover, roughly 2kg/mm more spring, and a valving curve that controls big single hits – kerbs, compressions, bumpy apex strips – without turning the cabin into a wheelbarrow. The settings come straight out of XYZ’s Top Sport race experience, then dialled back for the road.

Fitment for the Bmw X4 (2018-2026)

This kit fits the G02 X4 chassis with xDrive (4WD) running OE electronic damping, model years 2018 through 2026. The cancellation harness for the adaptive damper module is included in the kit, so the standard EDC fault routine is properly suppressed. Chassis code BM116-C.
