XYZ Racing Super Sport Coilovers — BMW Z4 6 CYL (NON 3.2) (Cancellation Kit for Electronic Damping) 2009-2016

The Z4’s front-engine, rear-drive layout puts a straight-six over the front axle and expects the rear to do the work under power, which is exactly where a soft factory spring rate starts to show its limits once you’re pushing on a b-road or a track day. XYZ Racing’s Super Sport coilover is built to give that platform a firmer, more controlled base without turning the ride harsh on the drive home.

Because this fitment carries the cancellation kit for electronic damping, it’s aimed specifically at Z4 6-cylinder cars built with factory electronic damper control – the kit removes that system from the loop so the Super Sport’s own valving does the work instead, cleanly, with no warning lights or conflicting signals from the original module.

What this coilover does for your 2009-2016 Bmw Z4

Ride height is adjustable front and rear, so you can correct the stance and recover any droop in geometry from age or wear before you even touch damping. The 36-way adjustment then lets you tune compression and rebound independently of ride height – wind it softer for a motorway cruise, firmer for a trackday session, without swapping parts. On a chassis that already carries its weight over the front wheels, a stiffer, better-controlled spring rate reduces the nose-dive under braking and the roll you’d otherwise feel loading the outside front tyre through a fast direction change. Because the electronic damper system is cancelled rather than fought against, the ride stays consistent lap to lap instead of the ECU trying to intervene against a damper it no longer recognises.

About the Super Sport coilover

The Super Sport damper is built to take the harshness out of rough or broken road surfaces while still giving you a genuine performance setup underneath. It runs 36-way damping adjustment alongside independent ride height control, so the same kit can be set up soft for daily use and wound up firm for a weekend on track without any parts changes. That range is the point of the design – one damper covering commuting, fast road driving and circuit days rather than forcing a choice between comfort and control. The cancellation-kit variant on this listing carries the same internals and adjustment range as the standard Super Sport, with the added hardware needed to run cleanly on Z4 models that left the factory with electronic damping control.

Fitment for the Bmw Z4 (2009-2016)

This kit is built for the Bmw Z4 6-cylinder range (chassis code BM74-1-C), excluding the 3.2, across the 2009 to 2016 production run, and specifically for cars fitted with the factory electronic damping system. The cancellation kit is included so the original electronic damper control is disengaged in favour of the Super Sport’s manual 36-way adjustment.
