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

The E89 Z4’s folding hardtop puts more mass over the rear axle than the soft-top roadsters it replaced, and on the 4-cylinder cars the turbocharged four up front carries noticeably less nose weight than the inline-six versions sold alongside it. Factory Electronic Damper Control was tuned around that specific balance, constantly adjusting valving through software. Fit fixed-valve coilovers without addressing that system and the dash fills with fault codes for sensors that no longer exist.

XYZ Racing’s Street Advanced kit for the 2009-2016 BMW Z4 4 CYL is built with that in mind, and this version bundles the cancellation kit needed to silence the factory EDC wiring so the car runs cleanly on manually set damping. Street Advanced itself sits in XYZ’s range as the fast-road and track-day spec, giving the Z4 adjustable comfort without asking the owner to commit to a full motorsport setup.

What this coilover does for your 2009-2016 BMW Z4

Once the EDC cancellation kit is fitted, the car stops fighting itself over which damping curve to run and instead holds whatever setting you dial in. On a chassis that already leans towards a rearward weight bias with the roof up, a fixed, well-chosen damping rate keeps body movement in check through direction changes without the front axle feeling disconnected from what the rear is doing. Ride height becomes adjustable independently of damping, so the nose-light stance the 4-cylinder Z4 is prone to can be levelled out to suit the car rather than left to sag on tired factory springs. The 720-way damping adjustment gives enough range to soften things for motorway miles and firm them up again before a track day, all through the same set of dampers.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s volume model, refined over several years of development and put through testing across race series worldwide before reaching production spec. It is built for cars that split their time between normal road use and the occasional track day, rather than for a car that lives permanently on slicks. The headline figure is 720 damping adjustment increments, giving a wide enough spread to move from a compliant daily setting to something firmer for a circuit session without swapping components. XYZ position it as core equipment for drivers who want genuine control over how the car sits and moves, not just a lowered ride height. Construction follows the same monotube-style approach used across the range, aimed at consistent damping response rather than a single fixed compromise.

Fitment for the Bmw Z4 (2009-2016)

This kit is specced for the BM73-1-C chassis code, covering 4-cylinder Z4 models built between 2009 and 2016. It is the cancellation-kit variant, meaning it includes the parts required to disable the factory Electronic Damper Control system on cars originally fitted with it, so the coilovers can run without triggering EDC-related warnings.
