XYZ Racing Tarmac Rally Coilovers — BMW 6 SERIES E63 / E64 M6 (Cancellation Kit for Electronic Damping) 2004-2010

The E63 M6 is a heavy GT with an S85 V10 hanging over the front axle and a factory EDC system that flattens every input through a filter the chassis never really needed. Strip the electronic damping out, bolt in a proper mechanical coilover, and the car finally tells you what 500bhp and 1710kg are doing through the contact patch.

This XYZ Racing Tarmac Rally kit for the 2004-2010 E63/E64 M6 is built for sealed-stage work – fast B-roads, rally tarmac, the kind of crested, broken surface that exposes any damper running out of stroke. The cancellation kit is the part that matters: it tricks the original EDC ECU so the dashboard stays quiet while a fully adjustable, mechanically damped strut does the actual work underneath.

What this coilover does for your 2004-2010 Bmw 6 SERIES E63 / E64 M6 (Cancellation Kit for Electronic Damping)

The first thing you notice on an M6 with the EDC deleted is mid-corner composure – the car stops floating between damping modes and settles into one honest rate. Compression and rebound adjustment let you build in enough low-speed control to keep the nose tied down under trail braking, while the Tarmac Rally valving keeps the rear axle planted when the surface breaks up. Over crests and compressions the damper has the stroke to absorb a hit without packing down, so the V10’s weight stops pitching the chassis around at corner exit. Spring preload and height adjustment let you set a proper rally-spec ride height that clears genuine UK road camber without scraping the front splitter every driveway. The cancellation harness keeps the OEM warning lights and dashboard clusters dormant, so the cabin is unchanged.

About the Tarmac Rally coilover

The Tarmac Rally is XYZ Racing’s sealed-stage damper, built around the brief that broken tarmac demands more travel and more compliance than a circuit-only setup will tolerate. The valving is drawn directly from XYZ’s own tarmac rally programme – the settings the company runs on its competition cars are the same settings shipped in this kit. Construction is geared toward absorbing big single hits without bottoming, suppressing secondary body movement after the impact, and keeping the tyre loaded so traction holds through the second half of the corner. The cancellation module is included specifically for the M6 because the factory EDC strut housings won’t accept a mechanical coilover without electronically faulting the car. Adjustability covers ride height, spring preload and damping, so the kit can be set up for fast road use as easily as a closed-stage rally car.
