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

The E90 M3’s S65 V8 spins to 8,400rpm and rewards a chassis that stays flat and communicative right up to that limit, but the factory EDC electronic dampers are tuned around a road-going compromise, not a fixed circuit set-up. The XYZ Racing Circuit Master coilover, in this Cancellation Kit for Electronic Damping specification, replaces that whole system so the M3’s own electronics stop fighting a manually set damper, giving sustained circuit lap-time work a fully mechanical foundation instead.

This is XYZ’s Circuit Master line – the dedicated track-day and race spec, not a fast-road halfway house. For a car built to be driven hard between 7,000rpm and its 8,400rpm limit, body control needs sorting before that top end is any use on a circuit, and this kit is built around exactly that job on the E90 M3’s chassis.

What this coilover does for your 2007-2011 BMW 3 Series E90 M3

Fit the Circuit Master and the E90 M3 stops leaning so hard on its standard anti-roll response under trail-braking into slower corners – independent adjustment across 9720 damping combinations lets you set compression and rebound apart from each other, so turn-in can be firmed up without turning the car into a kerb-strike machine on a bumpier circuit like Cadwell or Snetterton. Because the Cancellation Kit removes the factory EDC control loop entirely, there’s no electronic damper working against your manual setting mid-corner – what you set at the knob is what the rear axle actually does, session after session. Ride height drops through the threaded body, pulling the roll centre back in line with a lowered stance and sharpening turn-in without the wallow the standard spring and bushing combination allows once track temperatures build.

About the Circuit Master coilover

XYZ built Circuit Master as its circuit-only damper line, developed alongside the racing teams it supplies internationally rather than as a showroom upgrade. Each unit offers 9720 individual adjustment combinations across three external knobs – enough range to move from a wet-qualifying set-up to a dry sprint set-up on the same car without swapping parts. That figure comes from a genuinely fine damping curve rather than a marketing number: the internals use a small-orifice oil path, and on a rough road that path can produce a faint tick or hum as oil moves through it under low-speed compression. That’s a normal by-product of a valve tuned for circuit-smooth surfaces, not a fault, and it settles down once the car is back on track. XYZ’s own testing across international circuits shaped where those 9720 combinations sit, aimed squarely at drivers chasing a result rather than a comfortable commute.

Fitment for the BMW 3 Series E90 M3 (2007-2011)

This kit is coded BM89-C for the BMW E90 M3 saloon built between 2007 and 2011. It’s the Modified Rr Integrated, Cancellation Kit for Electronic Damping variant – specify this exact SKU only if your M3 carries the factory electronic damping control that needs cancelling out for a manual coilover to run correctly, rather than the standard non-EDC Circuit Master fitment.
