There’s modified, and then there’s built - this E92 M3 sits firmly in the latter camp.

It’s a car that was developed with clear intent, using the right parts, and maintained without compromise. It’s backed up by a substantial history file documenting both the build and ongoing upkeep… it’s all there.

At its core, it’s still everything that makes an E92 M3 special. But here, it’s been taken several steps further. The headline figure comes from the engine. An ESS 625 supercharger kit lifts the S65 V8 to 621bhp, paired with an Akrapovič Evolution titanium exhaust system. The result is exactly what you’d hope for: a sharp, responsive, and properly aggressive car when you put it to work.

Crucially, it hasn’t just been tuned for numbers. Supporting upgrades include uprated throttle actuators, reinforced rod bearings and bolts, RPI air scoops and a revised intake setup. It’s been built to handle the power properly.

But the chassis is where the real depth lies, KW Clubsport coilovers with uprated springs (specified to Team Schirmer recommendations) sit alongside Clubsport top mounts and full Schirmer kinematics. The subframe has been refreshed with solid bushings, the differential mounted on Powerflex, and transmission joints renewed. It’s a setup for precision and feedback above all else.

Two wheel and tyre setups come with the car. For the road, 19-inch Competition wheels on Michelin Pilot Sport 4S, and for track use, 18-inch Apex VS-5RS with Dunlop Direzza DZ03G.

Braking is equally well considered. A Brembo big brake kit with 380mm discs - 6-pot front, 4-pot rear - paired with Endless endurance pads, braided lines and Motul RBF660 fluid. Add in dedicated brake cooling ducts, and it’s a system designed for repeated hard use.

Visually, it looks the business: carbon fibre features throughout, bonnet vents, GT4-style front splitter, side skirt extensions, rear diffuser and GTS spoiler. Paint wise, it’s what you’d expect from a car used on the track, the high impact areas do have stonechips but the rest of the paintwork presents very well.

Inside, it’s been brought up to full LCI specification, with updated infotainment and lighting. M Performance seats, Alcantara trim throughout and a Performance LED steering wheel give it a focused, motorsport-inspired feel. Additional gauges for boost, EGT, oil pressure and temperature are neatly integrated, alongside a Macht Schnell distribution block. Everything is there for a reason.

The car has been professionally set up, corner weighted and aligned for track use, though can easily be dialled back for fast road driving.

Most importantly, this is a no-expense-spared build. Serviced diligently - often more than once a year - and supported by a comprehensive history file, it’s been maintained to the same standard it was built to.

As ever, we have a full digital file available on request, including additional images, walkaround videos, and service history scans. The car is available to view by appointment at our West London showroom.
