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

The E93 M3 carries a folding hardtop that the coupe body never had to, and that extra mass sits high and behind the rear axle, right where a cabriolet shell is already working hardest to stay flat through direction changes and resist scuttle shake over broken surfaces. XYZ Racing’s Top Sport coilover is built for owners who want to close that gap without turning the car into a trailer queen – a spec aimed at occasional track days as much as a fast B-road on a Sunday.

This particular kit is set up for the E93 M3 as sold with BMW’s factory electronic damper control, and it includes the cancellation kit needed to run the coilover’s own valving in place of the car’s damping ECU instead of fighting it every time the system tries to recalibrate.

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

With the factory EDC bypassed by the included cancellation kit, damping response comes from the coilover itself rather than a computer guessing at road surface every few milliseconds – which matters on a chassis carrying convertible reinforcement and hardtop mechanism weight that the coupe’s suspension tune was never asked to manage. Increased spring rate over the standard S65-equipped setup pulls in body roll under the sort of direction changes an open-top car naturally resists less well, and the added damping force keeps the extra mass settled rather than continuing to move after the chassis has already changed direction. Ride height is adjustable independently front and rear, so the nose-heavy V8 layout can be balanced against the weight sitting over the rear axle. The result is a car that turns in with less lean and puts power down out of a corner with less of the wallow a soft-top platform is prone to when left on standard springs.

About the Top Sport coilover

XYZ Racing’s Top Sport line steps damping force up by roughly 30 to 50 percent over its street-oriented settings, or alternatively runs a spring rate around 2kg/mm firmer, specifically to deal with the impact loads of uneven tarmac and larger bumps without the chassis pitching or the body continuing to move after the input has passed. That extra control is aimed squarely at keeping the tyre’s contact patch loaded and working rather than skipping across a surface, which is where the stability gain actually comes from rather than from stiffness alone. The valving and spring combination for this range comes directly out of XYZ Racing’s own Top Sport racing programme, carried over rather than softened for road use. It is built for track day sessions and for drivers who push on during a spirited road drive, not for a car that only ever sees a supermarket car park.

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

This kit is mapped to chassis code BM91-C, covering the E93 M3 from 2007 to 2011, in the modified rear-integrated configuration with the cancellation kit for the car’s electronic damping system included. Confirm your car left the factory with adaptive M dampers before ordering the cancellation kit variant – standard, non-EDC E93 M3s should use the base Top Sport listing instead.
