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

The F26 X4 was BMW’s awkward middle child – a coupe-SUV riding on the F25 X3 platform with a 1.7-tonne kerb weight, a high centre of gravity, and factory EDC dampers that prioritised compliance over body control. Lift that mass into a fast corner and the standard car rolls, the nose washes wide, and the xDrive system spends its day papering over a chassis that was never set up to be driven hard. The Top Sport kit is XYZ Racing’s answer for owners who want the X4 to actually corner like the sport-coupe BMW’s marketing claimed it was.

This is also where the supplied cancellation kit matters: the F26’s electronic damping module throws faults the moment you unplug factory struts, and the bundled EDC delete eliminates the dash warning without a coding session. Fit the kit, drive away, no error lights.

What this coilover does for your 2014-2018 Bmw X4

Spring rates lifted roughly 2kg/mm over the OE setting and damping firmed up by 30-50% give the X4 a body that actually settles between direction changes instead of pitching across two seconds of slop. The 30-step damping adjuster lets you firm things up for a B-road or an airfield day, then back the clicks off for the motorway home – the same kit covering both ends of the X4’s split personality. Ride height is independently adjustable from the spring perch, so you can drop the stance for the look without pre-loading the spring and ruining the travel. Turn-in is sharper, mid-corner roll is contained, and the xDrive system finally has a platform stable enough for the front axle to bite cleanly under power.

About the Top Sport coilover

Top Sport sits where XYZ Racing’s circuit experience meets a road car that still has to live with British tarmac. Spring rates are pitched roughly 2kg/mm above street tune and damping is set 30-50% firmer, with the explicit brief of absorbing big hits without unsettling the chassis and increasing tyre contact across uneven surfaces. The body is a monotube design with 30-position damping adjustment, independent ride-height control, and pillowball top mounts where the application allows. All settings draw directly from the brand’s Top Sport race programme, which is why the kit reads as track-capable on paper but stays driveable when you point it at the school run on Monday. It is built for owners who want occasional track-day pace without sacrificing the ability to use the car every day.

Fitment for the Bmw X4 (2014-2018)

This kit is specific to the F26 X4 in xDrive (4WD) form, chassis code BM105-C, covering production years 2014 to 2018. It includes the cancellation harness required to delete the factory Electronic Damping Control module, so vehicles originally fitted with EDC will fit without throwing a dash fault.
