XYZ Racing Street Advanced Coilovers — BMW 6 SERIES E63 / E64 M6 2004-2010

The E63 M6 hides a 5.0-litre S85 V10 over its front axle and a heavy GT body behind it, and the factory EDC suspension was always a compromise between cosseting a £80k flagship and containing 500bhp through a corner. The XYZ Racing Street Advanced is the kit that lets you keep this car usable on a British B-road while finally giving the front end the body control its chassis has always deserved.

Pitched at the owner who still drives their M6 on real roads but wants the option of a Bedford or Cadwell day without floating through Hawthorn, the Street Advanced sits between a comfort coilover and a full circuit setup. For a 1710kg V10 coupe or cabriolet, that middle ground is exactly where the platform wants to live.

What this coilover does for your 2004-2010 Bmw 6 Series E63 / E64 M6

Lowering an M6 onto a properly valved coilover transforms how the nose loads under braking into a roundabout – the dive that the standard EDC dampers can’t fully arrest is gone, and the steering loads up earlier. With 720 damping settings on tap you can run it soft enough that motorway expansion joints don’t crash through the cabin, then wind on compression and rebound for a track session without touching ride height. Body roll through long, loaded corners drops noticeably, which matters on a car whose rear axle carries a torque-vectoring SMG-shifted V10 trying to push the tail wide. Stance drops cleanly over the staggered 19s without resorting to camber shims, and the heavier E64 convertible benefits even more from the added structural feel a stiffer damper gives a soft-top chassis.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s most popular kit and the one their development team has iterated on for years, refined through testing in international race series before being adapted for road and track-day use. The defining feature is the 720-way damping adjuster – a single knob that bridges fast-road compliance and circuit-grade control without the complexity of a separate bump and rebound system. Construction is built around the same monotube architecture XYZ runs across its competition catalogue, with ride-height adjustment independent of spring preload so corner-balancing the M6 doesn’t cost you suspension travel. The spring rates are picked specifically for a chassis carrying a V10 up front and a full GT interior behind, not generic numbers ported across from a lighter platform. It is the kit XYZ themselves describe as essential equipment for drivers chasing speed and control without giving up the ability to drive home afterwards.
