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

The F83 M4 convertible left the factory running BMW’s electronically controlled M Adaptive dampers, which means any aftermarket kit either has to work with that system or replace it outright. This Super Sport kit does the latter: it includes the cancellation kit needed to take the factory electronic damper control unit out of the loop, so the car runs on the coilover’s own 36-way manual adjustment instead of BMW’s software making the calls.

That matters more on the F83 than it does on the coupe. Losing the fixed roof costs the shell some torsional stiffness, so BMW leaned on extra bracing through the sills and rear subframe mounts to hold things together, and the folding roof mechanism adds weight over the rear axle. A Super Sport spec set up for fast-road and weekend track use lets you tune that added mass and flex out through ride height and damping, rather than living with the factory compromise.

What this coilover does for your 2014-2020 Bmw 4 Series F83 M4 (Modified Rr Integrated) (Cancellation Kit for Electronic Damping)

Cancelling the factory electronic damping means ride quality and body control on your F83 M4 come entirely from how you set the 36-way dampers, not from an adaptive module second-guessing you mid-corner. Firm the compression up and the extra weight the convertible carries over the rear stops translating into float under hard braking into a corner; back it off for a motorway run and the kit still resolves rough B-road surfaces without the harshness a fixed factory sport setting would give you. Ride height adjustment lets you correct the standard car’s stance once you’ve lowered it, keeping the front end working through the geometry as intended rather than fighting a ride height that was originally set up around the factory dampers. For a chassis that’s already compensating for losing its roof, having direct, computer-free control over both ends of the damper is the whole point of running this kit.

About the Super Sport coilover

XYZ Racing’s Super Sport damper is built to take the harshness out of rough British roads without dulling response when you actually want it. It runs 36-way damping adjustment across the range, giving a far finer window to work with than the handful of modes a factory electronic system offers, and ride height is independently adjustable so you can set stance and corner weights without disturbing spring preload in isolation. Because the F83 comes from the factory with electronic damper control, this fitment ships with the cancellation kit that removes that module from the wiring, so the Super Sport dampers aren’t fighting a system still trying to talk to actuators that are no longer there. That’s the split use this M4 sees day to day: rough, imperfect road driving most of the time, with enough adjustment range to firm everything up for a track day without swapping any parts.
