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

The E63 M6 was sold on the promise of its S85 V10 and seven-speed SMG, but the chassis underneath has always been the harder problem to solve. At 1,785kg with a long wheelbase and a nose loaded by that 5.0-litre V10, the standard EDC setup gets vague the moment you ask it for sustained lateral load – and once the electronic dampers start to age, the car develops a float that no amount of geometry work will cure. This XYZ Racing Street Advanced kit is the answer for owners who want to retire the EDC system entirely and run a proper mechanically adjustable setup on the road and the occasional track day.

Crucially, this variant ships with the cancellation kit for the M6’s electronic damping circuit, so the car’s ECU stops throwing faults the moment the original struts come out. You get a coilover that bolts in cleanly to the E63/E64 hardware without leaving a dashboard warning lit up on every drive home.

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

Drop the EDC dampers and the M6 finally feels like the GT-with-teeth it was always supposed to be. The 720 damping positions let you set the car up firm enough to keep the nose tied down through a fast B-road sequence, then back the rebound off for a long motorway run without the secondary ride breaking up over expansion joints. Turn-in sharpens noticeably once the float of the worn EDC struts is gone, and trail-braking into a third-gear corner stops being an act of faith. Ride height comes down to clean up the arch gap that the factory rake exaggerates on the coupe, and the cancellation kit means none of this comes at the cost of permanent dash warnings or limp-mode behaviour.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s most-developed product line and the kit the company tunes hardest for dual-purpose road and track-day use. It is the result of years of iterative work by their in-house engineering team and has been validated in international race programmes before being signed off for road sale. The headline figure is 720 ways of damping adjustment from a single knob per damper, which is more granularity than most owners will ever exhaust but gives genuine room to chase a setup as tyres, weather and route change. Construction is built for repeat heat cycles rather than a single shakedown lap, and the package is aimed squarely at drivers who want the car to respond to spec changes rather than mask them.

Fitment for the Bmw 6 SERIES E63 / E64 M6 (Cancellation Kit for Electronic Damping) (2004-2010)

This kit is matched to the E63 coupe and E64 convertible M6 chassis (XYZ code BM47-C) for the 2004 to 2010 production window. It is the specific variant supplied with the electronic damping cancellation harness, so the original EDC control unit can be retired without leaving the car in a fault state.
