XYZ Racing Tarmac Rally Coilovers — BMW X4 F26 4WD (Cancellation Kit for Electronic Damping) 2014-2018

The F26 X4 is a 1.8-tonne crossover riding on BMW’s adaptive Dynamic Damper Control – a system designed to keep a tall, heavy SAV composed on the road, not stitched together across a broken tarmac stage. Lift it out of that comfort envelope and onto a sealed rally surface and the standard setup runs out of travel, runs out of compression control, and the electronic dampers start fighting inputs they were never tuned to receive.

The XYZ Racing Tarmac Rally coilover for the BMW X4 F26 2014-2018 replaces that whole compromise with a damper specifically built to absorb stage impacts while keeping a 4WD chassis planted. The included cancellation kit takes the EDC module out of the loop cleanly, so the car stops reporting suspension faults the moment the OEM struts come off.

What this coilover does for your 2014-2018 BMW X4 F26

The biggest change you’ll feel is the F26 finally sitting still over surface breaks instead of pattering and floating. Compression damping is tuned to swallow the jolt of a kerb strike or a mid-corner crest without unloading the inside wheel, which on a 4WD platform means the centre diff keeps a useful contact patch to push torque through. Rebound is held back enough that the body doesn’t pogo after a fast compression – critical on a tall-riding chassis where weight transfer is already working against you. Tyre traction goes up, the steering settles, and the car stops feeling like it’s reacting two tenths after the input. The cancellation kit removes the EDC dash warnings entirely, so you don’t drive a sealed stage with a strut-fault light in your peripheral vision.

About the Tarmac Rally coilover

Every setting on this damper comes from XYZ Racing’s own Tarmac Rally programme – the valving, the spring pairing, the bump and rebound balance are all derived from stage running rather than circuit lap time. The brief is uneven pavement: surface joins, patched repairs, mid-corner bumps that would unsettle a stiffer circuit setup. Construction prioritises impact absorption without losing body control, so heavy compression hits don’t translate into a wallowing rebound stroke. The result is a damper that suppresses shock movement through the bodyshell, keeps the contact patch loaded under provocation, and gives the driver a predictable platform to lean on through stage sections where the road surface itself is the variable. Spring rates and damper tune are matched to the F26’s weight and 4WD layout rather than borrowed from a lighter chassis.

Fitment for the BMW X4 (2014-2018)

This kit fits the F26 X4 with the 4WD drivetrain across the full 2014-2018 production span, chassis code BM105-C. The cancellation harness is specific to cars originally fitted with Electronic Damping Control and clears the EDC fault codes once the OEM struts are removed.
