XYZ Racing Super Sport Coilovers — BMW 4 SERIES F33 4/6 CYL (excl. M-Technik. xDrive & EDC) 2013-2026

The BMW F33 4 Series Convertible carries more weight than its F32 coupe sibling, and without a folding steel roof the shell leans harder on the subframe and suspension geometry to keep body flex in check through direct-load corners. The XYZ Racing Super Sport coilover kit replaces the factory passive dampers on 4- and 6-cylinder F33 cars built without M-Technik, xDrive or Electronic Damper Control, swapping in a fixed, mechanically-adjustable platform in place of the standard setup.

Super Sport sits between XYZ’s road-focused and full competition ranges, built for owners who split their time between fast A-roads and the occasional track day. On a rear-wheel-drive F33 running the base suspension architecture, that means a kit you can wind up for a trackday morning and back off again for the drive home.

What this coilover does for your 2013-2026 BMW 4 Series F33

Fit this kit to a 2013-2026 BMW 4 Series F33 and the first thing you’ll notice is how much of the convertible’s body movement disappears under load. The Super Sport’s 36-way damping adjustment lets you firm up compression and rebound to control the extra mass a drop-top carries over the coupe, cutting the float that shows up mid-corner on the standard dampers. Ride height adjusts independently at each corner, so you can drop the F33’s stance and correct the geometry that shifts when you lower a car this way, instead of just winding the springs down and hoping for the best. Because this car doesn’t run factory EDC, there’s no adaptive damper working against your chosen settings – whatever adjustment you land on stays put until you change it again. On UK roads that means sharper turn-in without the ride turning brittle over broken tarmac, and a car that settles faster after a compression than it did on the factory setup.

About the Super Sport coilover

XYZ’s Super Sport damper is built around a body with 36 stages of damping adjustment, giving a far wider working range than the two- or three-position adjusters found on cheaper coilover kits. Ride height is set independently of spring preload through a threaded body, so lowering the F33 doesn’t automatically stiffen or soften the ride the way a preload-only system does. Reducing harshness over rough surfaces is one of the design goals behind the damper – it’s tuned to take the edge off expansion joints and patched B-roads without losing body control when you load it up hard. That range is what lets the same kit cover a car used for a weekend track session and the same car doing the school run the rest of the week, rather than forcing a compromise toward one or the other. On a heavier convertible body like the F33, that adjustment range matters more than it would on the coupe, because there’s more mass for the damper to control on turn-in and under braking.

Fitment for the BMW 4 Series F33 (2013-2026)

This kit is built specifically for the BMW 4 Series F33 on the BM75-9 platform, covering 4- and 6-cylinder cars from 2013 to 2026. It’s designed for cars without the M-Technik suspension package, without xDrive four-wheel drive, and without factory Electronic Damper Control – confirm your car doesn’t carry any of those three options before ordering, as the geometry and damper mounting differ on those variants.
