XYZ Racing Super Sport Coilovers — BMW Z4 4 CYL (Cancellation Kit for Electronic Damping) 2009-2016

The Z4 E89’s factory-fit adaptive dampers tie ride height and damping curve to a control module reading wheel speed and steering angle, which is exactly why swapping a four-cylinder Z4 onto coilovers isn’t a simple springs-and-shocks job. This Super Sport kit ships with the cancellation kit built in, so the electronic damping control wiring is accounted for and the car won’t throw a fault or drop into a limp damping map once the factory actuators are unplugged.

Super Sport is XYZ Racing’s fast-road and weekend track spec – stiffer and more adjustable than a comfort-biased kit, but still liveable on the commute. On a roadster this light, with the four-cylinder up front keeping weight off the nose, a coilover that lets you set both ride height and damping properly is the difference between a car that just sits lower and one that actually turns better.

What this coilover does for your 2009-2016 BMW Z4 4-cylinder (EDC cancellation kit)

With the electronic dampers cancelled out, damping response goes back under your control rather than a module’s, and the 36-way adjustment gives enough range to run soft for a wet B-road one weekend and firm for a track day the next. Independent ride height adjustment lets you drop the Z4’s stance without chewing into the fast-road travel a roadster this light still needs over broken surfaces. Because the E89 four-cylinder carries less weight over the front axle than the six-cylinder cars, the extra front support this kit provides sharpens turn-in without tipping the balance into nervousness. The retractable hardtop adds weight high in the body, so tighter, better-controlled damping also settles the car faster after a direction change.

About the Super Sport coilover

Super Sport is built around a monotube damper design and 36 discrete damping settings, giving a far finer window of adjustment than a fixed-rate or single-adjuster setup. The stated design goal is straightforward: take the harshness out of poor road surfaces while still holding the car flat when you lean on it, and let ride height be set independently of spring preload rather than compromising one for the other. XYZ positions Super Sport as dual-purpose – the damping range and construction are pitched to cope with a full weekend of circuit laps, then drop back down for the drive home and the daily commute in between. It’s the mid-point in the XYZ Racing range: firmer and more adjustable than a fast-road-only kit, without the single-minded stiffness of a dedicated track coilover.

Fitment for the BMW Z4 4-cylinder (2009-2016)

This kit is built for the Z4 four-cylinder, internal chassis reference BM73-1-C, covering the 2009 to 2016 model years. It’s the cancellation-kit variant specifically for cars fitted with electronic damping control from the factory – if your Z4 has EDC, this is the correct kit rather than the standard Super Sport listing.
