XYZ Racing Circuit Master Coilovers — BMW I8 4WD (Cancellation Kit for Electronic Damping) 2014-2020

Cancelling the I8’s factory electronic damping is the first job any coilover has to solve, and this Circuit Master kit is engineered around exactly that. Supplied as a cancellation package for the 2014-2020 Bmw I8 4WD, it removes the adaptive struts and the car’s dependence on its electronic damping control, freeing the chassis to run fixed, mechanically adjustable damping instead.

That matters on a car this unusual. The I8 splits its drive between an electric front axle and a turbocharged triple at the rear, wrapped in a carbon-fibre tub, so its balance shifts as the two power sources hand over. The Circuit Master series is built for sustained circuit lap-time work, and on the I8 it gives you the control to set the car up for the track rather than the road-biased compromise it left the factory with.

What these coilovers do for your 2014-2020 Bmw I8 4WD

Once fitted, the first thing you feel is body control. With three separate adjustment knobs offering up to 9720 combinations of damping, you can settle the I8’s nose over kerbs and under trail-braking without the float the standard adaptive setup allows. Ride height drops to suit the car’s low front, sharpening turn-in and giving the electric front axle a more planted contact patch. Compression and rebound are tuned independently, so you can firm up support for high-speed direction changes while keeping enough mechanical grip for slower, technical corners. The result is a car that holds its attitude under load and stays predictable as the petrol and electric drive trade off mid-corner.

About the Circuit Master coilover

The Circuit Master sits at the competition end of the XYZ Racing range, sharing its design approach with the brand’s Racing Spec, Drift Spec and Tarmac Rally builds. It has been tested by XYZ racing teams across international circuits, and the headline feature is its breadth of adjustment: three adjustment knobs combine to give 9720 distinct damping settings, enough to fine-tune the car for almost any track layout. The valving uses a small oil-hole passage, which means that over large bumps you may hear a faint noise as oil moves through the restricted port – this is normal, a by-product of the design rather than a fault. As the name suggests, this is a coilover engineered specifically for circuit use, where surfaces are smoother and the priority is consistent damping under repeated heavy loads.

Fitment for the Bmw I8 4WD (Cancellation Kit for Electronic Damping) (2014-2020)

This kit is specified for the Bmw I8 4WD built between 2014 and 2020, catalogued under XYZ chassis reference BM102-C. It is supplied as a cancellation kit for the factory electronic damping system, so it is the correct option for cars running BMW’s adaptive dampers as standard. Confirm your build year falls within the 2014-2020 span before ordering.
