XYZ Racing Racing Spec Coilovers — BMW 3 SERIES E93 M3 (Modified Rear Integrated) (Cancellation Kit for Electronic Damping) 2007-2011

The E93 M3’s folding hardtop adds real mass over the rear axle and takes away some of the torsional stiffness the fixed-roof E92 coupe keeps, so a cabriolet built for serious circuit work has to manage body flex and rear-end mass before the S65 V8’s power ever gets a fair fight with the road. Racing Spec coilovers are built for exactly this brief: track and time-attack sessions where the chassis needs to stay flat and predictable lap after lap of hard braking and direction changes.

This fitment is the cancellation-kit version for E93 M3s built with factory electronic damping control, where the rear mounts have been reworked to integrate a fixed, manually adjustable racing damper in place of the electronic unit. That matters on a convertible chassis already carrying extra weight aft of the rear axle – it removes the electronic system’s variability and replaces it with damping you set once and trust.

What this coilover does for your 2007-2011 BMW 3 Series E93 M3

Cancelling the factory electronic damping and integrating the Racing Spec unit into the rear mount gives you a fixed damping curve that doesn’t hunt between comfort and sport modes mid-corner – useful on a car where the extra hardtop weight already asks more of the rear axle under trail-braking. Lowering the ride height brings the centre of gravity down and tightens body control through direction changes, which helps offset the reduced chassis rigidity of the drop-top body versus the coupe. Manual adjustment lets you firm up compression and rebound for a circuit day, then wind it back for the drive home, without the car second-guessing your inputs through an ECU. On a car carrying the S65 V8 over the front axle, sharper front-end response to steering input keeps corner entry consistent as speed builds through a session.

About the Racing Spec coilover

Racing Spec damping comes directly from XYZ Racing’s motorsport programme, with valving settings pulled from real WTCC competition rather than road-car estimates. Where a car has already had significant upgrades – bigger brakes, aero, a stripped interior, or other changes that shift how load moves through the chassis – XYZ Racing can build a bespoke shock absorber to suit, the same approach used for factory racing cars and A-class competition builds. That custom route works by supplying full details of what’s already been changed on the car and which circuit it’s aimed at, so the damper is valved for that specific combination rather than a generic track setting. For the E93 M3 cancellation-kit application, that means a damper engineered to replace the electronic unit outright, not simply override it.

Fitment for the BMW 3 Series E93 M3 (2007-2011)

Chassis code BM91-C covers the E93 M3 built from 2007 to 2011. This is the cancellation-kit variant for cars specified with factory electronic damping control, with rear mounts modified to integrate the Racing Spec damper in place of the electronic unit – confirm your car carries EDC before ordering this fitment rather than the standard rear mount version.
