XYZ Racing Tarmac Rally Coilovers — BMW 6 SERIES E63 / E64 M6 2004-2010

The E63 M6 is a heavy GT car asked to behave like a sports coupe, and on a broken British B-road or a sealed-stage rally route the standard SMG-era setup runs out of damper travel long before the S85 V10 runs out of revs. The Tarmac Rally kit is built for exactly that scenario: a 1,710kg chassis carrying a 5.0-litre V10 over surfaces that punish anything tuned only for smooth circuits.

For owners running an E63 or E64 M6 on rough tarmac stages, hillclimbs, or the kind of UK road that doubles as a stage in everything but name, this is the XYZ Racing damper engineered to keep the tyre planted when the road stops cooperating. It is not a track coilover repurposed – it is a separate type, with damping logic drawn from XYZ’s own rally programme.

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

The M6’s front-heavy weight distribution and long wheelbase mean that mid-corner bumps load the outside front damper hard, and a poorly matched coilover will skip the tyre across the surface and wash the nose wide. The Tarmac Rally damping absorbs the impact of uneven pavement and suppresses shock travelling into the body, so the contact patch stays loaded through the hit rather than unloading mid-corner. Over the kind of compressions that catch the M6’s nose – mid-corner crests, dropped manhole covers, patched apex kerbing – the chassis settles faster and the steering wheel stops kicking. On corner exit, with 500bhp from the S85 trying to overwhelm the rear axle, the additional rear-axle compliance keeps traction biting instead of breaking into wheelspin every time the road camber changes. The result is a car you can lean on confidently over surfaces where a stiffer track coilover would skip and a softer road kit would wallow.

About the Tarmac Rally coilover

The Tarmac Rally is purpose-tuned for sealed-stage rally use, where the surface is paved but never smooth. Where a circuit damper assumes flat, predictable tarmac, this kit is set up to absorb the jolt of large bumps and translate it into controlled body movement rather than transmitted shock. The damping curves come directly from XYZ Racing’s own tarmac rally experience, with valving that prioritises tyre compliance over outright low-speed stiffness. Construction follows XYZ’s standard coilover architecture – height-adjustable platform, damping adjustment, and the seal package needed to survive sustained use on debris-strewn surfaces. The brief was straightforward: build a damper that lets a competition driver carry speed across imperfect tarmac without sacrificing the body control needed to place the car on corner entry. Every setting in this kit reflects that priority.
