XYZ Racing Circuit Master Coilovers — BMW 3 SERIES E90 M3 (Cancellation Kit for Electronic Damping) 2007-2011

The E90 M3’s 4.0-litre S65 V8 sits high and forward of the front axle, and on a stock car you feel every kilo of it loading the outside front mid-corner. The Circuit Master is the answer when the M3’s factory EDC has either failed, become uneconomic to maintain, or simply isn’t giving you the platform stability a track-focused E90 needs over a 20-minute session at Cadwell or Donington.

This kit includes the cancellation hardware to retire the electronic damping module cleanly, so the dash stops complaining and the chassis stops second-guessing your inputs. What replaces it is a fully mechanical system with 9720 individual damping permutations – the kind of granularity that lets a circuit driver actually find a setting that suits the S65’s appetite for revs and the E90’s tendency to rotate hard on trailed brake.

What this coilover does for your 2007-2011 Bmw 3 Series E90 M3 (cancellation Kit For Electronic Damping)

Lower the M3 onto Circuit Masters and the first thing you feel is the front end stops washing wide under sustained load. The 9720-way matrix means bump, rebound and low-speed compression can be balanced independently, so you can finally separate kerb-strike absorption from mid-corner support – something the original EDC system fudged into a single algorithm. Front-end turn-in sharpens, the rear axle stays planted on power exit, and brake-induced dive flattens out enough that you can trail deeper into a corner without unloading the inside rear.

For drivers running semi-slicks or proper track rubber, the mechanical damping gives you something the EDC never could: repeatable behaviour. Every lap is the same lap, because nothing is electronically adapting in the background.

About the Circuit Master coilover

The Circuit Master is XYZ Racing’s most aggressive circuit specification, sitting in the same product family as the Racing Spec, Drift Spec, and Tarmac Rally builds. It runs three separate adjustment knobs – the layout XYZ uses to give a driver true independent control over the damping curve rather than the single-knob compromise found on entry-level kits.

The 9720-way adjustment count comes from the interaction of those three circuits, and the kit has been validated by XYZ racing teams competing on international circuits. Worth knowing: the small-oil-hole passage design that gives this damper its precision can produce a faint audible note when the coilover is forced over a sharp bump. That is by design and is documented by XYZ – the Circuit Master is built for the smoother surface of a sealed circuit, not for British B-roads.

Fitment for the Bmw 3 Series E90 M3 (cancellation Kit For Electronic Damping) (2007-2011)

This kit is built specifically for the E90 saloon M3 chassis (BM63-1-C) running the original EDC electronic damping system, model years 2007 through 2011. The included cancellation kit clears the factory EDC controller so the new mechanical dampers can run without throwing fault codes. Confirm your build year and verify your M3 was originally specified with electronic damping before ordering.
