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

The E93 M3’s factory EDC dampers work well until you start pushing the S65 V8 into sustained circuit sessions, at which point the electronic system’s narrow adjustment window becomes the limiting factor rather than the tyres. Swapping to a fully manual, mechanically adjustable platform removes that ceiling and hands full control back to the driver, which is exactly what sessions built around repeated hot laps demand rather than a single quick blast.

This kit pairs the Circuit Master coilover with the cancellation module needed to delete the factory EDC wiring cleanly, so the convertible’s chassis – already carrying more mass over the rear axle than the coupe – gets a damper that responds to spring load and body movement instead of a control unit guessing at road surface.

What this coilover does for your 2007-2011 BMW 3 SERIES E93 M3 (Modified Rr Integrated) (Cancellation Kit for Electronic Damping)

With 9720 combinations of damping adjustment available through the 3 external knobs, you can set compression and rebound independently front and rear to match the E93’s cabriolet-specific flex characteristics rather than accepting a compromise tune shared with the saloon. Reworking the rear settings addresses the way this chassis’s rear subframe and diff move under trail-braking and mid-corner load, which is where extra unsprung weight from the folding roof structure shows up first. Ride height becomes fully adjustable independent of spring preload, so you can correct the nose-up stance the standard EDC setup tends to leave and get the front axle loading evenly again. Removing the EDC solenoids also drops a measurable amount of unsprung mass at each corner, sharpening turn-in response on the S65-powered car without the electronic system hunting for a damping curve mid-corner.

About the Circuit Master coilover

XYZ Racing built Circuit Master as its top-tier platform for drivers running Racing Spec, Drift Spec or Tarmac Rally builds – cars doing repeated laps rather than the occasional trackday. The line has been developed and run by XYZ’s own racing teams on circuits worldwide, and the 9720-way adjustment range exists specifically so a team can retune between sessions rather than living with one compromise setting. Each damper uses a 3-knob external adjuster with a small-oil-hole metering design; on rough surfaces this can produce a faint noise as oil moves through the restricted passage, which is a normal characteristic of the valving rather than a fault, and it’s a non-issue on the smooth circuit surfaces the damper is built for. Construction is monotube, which keeps oil and gas separated for consistent damping force across a full lap rather than fade building session to session. For the E93, the kit includes the cancellation harness/resistor pack that lets the ECU run without the factory EDC modules present, so there’s no warning-light workaround needed after fitment.

Fitment for the BMW 3 SERIES E93 M3 (Modified Rr Integrated) (Cancellation Kit for Electronic Damping) (2007-2011)

Built for the E93 chassis code M3 convertible, model years 2007 to 2011, specified with the modified rear integration and EDC cancellation kit for cars leaving the factory electronic damping system fitted. Confirm your car carries the EDC-equipped M3 spec before ordering, as the cancellation hardware is matched to that wiring.
