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

The E89-generation BMW Z4 arrived in 2009 as a front-engine, rear-drive roadster with a folding hardtop, and the 6-cylinder non-3.2 cars carry a turbocharged straight six ahead of the windscreen that wants to load the outside rear hard the moment you get back on the throttle mid-corner. On broken, cambered tarmac stages that weight transfer shows up as a front end that goes light over crests and a rear axle that steps out if the damper can’t keep the tyre in contact with the road. The XYZ Racing Tarmac Rally coilover is built around that exact problem.

This kit is specified for the Z4’s non-3.2 six-cylinder cars fitted with factory electronic damping control, and comes with the cancellation kit needed to remove the EDC wiring from the equation so the car runs purely on the mechanical valving XYZ Racing has set for stage work. That means no conflict between an aftermarket damper and a factory computer still trying to adjust for a system that is no longer there.

What this coilover does for your 2009-2016 Bmw Z4 6 CYL (NON 3.2) (Cancellation Kit for Electronic Damping)

Fitted to a Z4 running a big turbocharged six, the Tarmac Rally coilover keeps the front axle loaded through direction changes instead of letting the nose skip across broken surfaces, which matters when a rally stage rarely offers a flat apex. The damper absorbs the jolt from potholes and edge cuts rather than transmitting it straight into the chassis, so the body stays settled and the tyre keeps working instead of skipping. That improved contact patch translates directly into traction out of tight, low-speed stage corners, where the Z4’s turbo six can otherwise overwhelm the rear tyres on a poorly controlled chassis. The cancellation kit removes any risk of the factory EDC system fighting the new valving, so the ride quality you get is exactly what XYZ Racing dialled into the hardware, not a compromise negotiated with the car’s original electronics.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s damper for sealed-stage tarmac events, built to soak up the hit from uneven road surfaces without passing that energy into the body shell. Where a broken road edge or a mid-corner bump would normally unsettle the car, this damper’s valving absorbs the impact and keeps the body from pitching, which in turn keeps the tyre’s contact patch doing its job rather than skating over the surface. The result is a car that holds its line and stays predictable through the compressions and camber changes that sealed tarmac stages throw up lap after service. Every damping setting on this kit comes directly from XYZ Racing’s own tarmac rally programme rather than a generic road-going baseline, so the valving reflects what the team has actually needed on stage rather than a theoretical setup.

Fitment for the Bmw Z4 6 CYL (NON 3.2) (Cancellation Kit for Electronic Damping) (2009-2016)

This kit is specified for the BMW Z4, chassis code BM74-1-C, covering the 6-cylinder non-3.2 cars built between 2009 and 2016. It is designed specifically for cars originally fitted with electronic damping control, and includes the cancellation kit required to run this coilover in place of the factory EDC hardware.
