XYZ Racing Tarmac Rally Coilovers — BMW 3 SERIES E93 M3 (Cancellation Kit for Electronic Damping) 2007-2011

The E93 M3’s folding hardtop puts roughly 200kg over the rear axle that the saloon and coupe never had to carry, and on a broken sealed stage that mass shows up as a rear that refuses to settle between corners. The Tarmac Rally coilover is built for exactly that problem: keeping the contact patch loaded when the surface stops being smooth and the S65 V8 is asking the rear tyres for everything they have.

This is the cancellation-kit variant, so the factory EDC electronic damping is taken out of the loop entirely and replaced with a fully mechanical, manually adjustable damper. No more compromise between the M3’s three EDC modes – the damping is whatever you set it to, stage by stage.

What this coilover does for your 2007-2011 Bmw 3 Series E93 M3 (Cancellation Kit for Electronic Damping)

On a tarmac stage the E93 M3 will load the outside front hard, unload the inside rear over a crest, then ask the suspension to recover before the next compression. The Tarmac Rally damping is tuned to absorb that big initial hit without packing down, then return the wheel to the road before the car gets light. You feel it in the front end staying planted on turn-in over patched repairs, and in the rear axle finding traction earlier on corner exit instead of skating sideways under V8 torque. Bump absorption is the headline benefit – the damper soaks the worst of a broken surface without translating it as a steering input – and the cancellation kit means the EDC dashboard light and fault codes are designed out, not bodged around.

About the Tarmac Rally coilover

The Tarmac Rally damper is engineered specifically for sealed-stage rally work – fast tarmac with bumps, crests, kerbs and surface changes that a circuit setup would never see. The valving prioritises absorbing a big single impact without the damper packing down on the next compression, which is the failure mode that ends rally stages. Body shock is suppressed to keep the tyre loaded and traction available, rather than letting the chassis pogo after a hit. Every damping setting in this kit is drawn from XYZ Racing’s own tarmac rally programme – settings developed on stages, not on a dyno. The cancellation kit element replaces the E93 M3’s EDC signal path with a passive harness, so the OEM ECU sees a healthy damper circuit while the actual damping is now mechanical and in your hands.
