XYZ Racing Top Sport Coilovers — BMW 4 SERIES F83 M4 (Cancellation Kit for Electronic Damping) 2014-2020

The F83 M4 Convertible carries a folding hard-top, extra bracing, and the structural penalty that comes with losing a roof – around 100kg over the F82 coupe, most of it sitting high and rearward. The factory Adaptive M suspension hides that mass well on smooth surfaces, but on a British B-road or a lumpy circuit kerb it betrays the car’s weight distribution with float over crests and a rear axle that wants to step before the front has finished loading. The XYZ Racing Top Sport coilover for the F83 M4 is the answer when you’ve decided the EDC system has reached the end of what software remapping can do for you.

This kit ships with the cancellation module for the electronic damping, so the car’s CAS module stops throwing warnings the moment you unplug the OEM struts. You get a fully passive, height-adjustable, damping-adjustable setup tuned for a car that gets driven hard at weekends and still has to behave on a school run.

What this coilover does for your 2014-2020 Bmw 4 Series F83 M4 (cancellation Kit For Electronic Damping)

Drop the convertible’s centre of gravity by 25-50mm and the M4’s chassis stops fighting itself in transitions – the car rotates from the middle rather than pivoting around a soft rear. Top Sport runs roughly 30-50% more damping force and around 2kg/mm more spring rate than a street-biased coilover, which is what the F83’s kerb weight actually needs to keep the S55’s torque from overwhelming the rear axle on corner exit. The adjustable damping knob lets you wind off a few clicks for the motorway home, then add them back in the paddock car park before a session. Turn-in sharpens, mid-corner attitude settles, and the rear stops feeling like it’s working on a delay.

About the Top Sport coilover

Top Sport is XYZ Racing’s circuit-and-street platform, and the spec sheet reads like a kit derived from their own race programme rather than a catalogue tick-box. Damping is multi-adjustable from the top of the strut, so you tune compression and rebound together without crawling under the arch. The construction is built to absorb the kind of impact a track kerb or a mid-corner ridge throws at a stiffly-sprung car – the goal is to suppress body shock and keep the contact patch loaded rather than skipping. Spring rates run 2kg/mm above street settings, with damping uprated to match, which is the combination that lets the car ride a poor surface without losing tyre temperature. Every setting here comes out of XYZ’s own Top Sport racing programme, and the platform is designed for track day use and aggressive road driving rather than a comfort-first commuter spec.
