Gone but certainly not forgotten, the BMW M3 E92 Coupe has been effectively replaced by the first ever M4 Coupe but that hasn’t stopped the German tuners at KBR Motorsport to work hard on the old version to make it worthy of the “Clubsport” suffix they applied. The first order of business was to put the car on a serious weight loss program and as you can see they removed the rear seats, sound insulation, trim and other bits and pieces to shave off weight as much as possible.
Moreover, even the trunk has been stripped out while the door panels are now manufactured from carbon fiber. For added stability, the tuner has bolted on a roll cage and they also replaced the standard front seats with Recaro’s pair of Profi SPG motorsport seats that come with four-point harness from Scroth.
After finalizing the interior, the engineers at KBR Motorsport focused on the car’s hardware and applied a Clubsport coilover suspension from KW while the stock wheels were removed to make room for a 19-inch set of BBS Competition alloys shod in 265/30 ZR19 Pirelli Trofeo tires which are ideal for track use. Hiding behind these wheels are the Endless discs and brake pads which provide superior braking power compared to a stock M3 E92 Coupe.
A tuning package would not be complete without a power bump, so the V8 4.0-liter engine has received a remapped ECU and other tweaks which have bumped output to no less than 450 bhp and a maximum torque of 440 Nm. The upgraded motor works with a revised gearbox benefiting from optimized software which grants faster shifts.
Aside from the new wheels, the exterior cabin hasn’t gone through any extensive changes, but KBR Motorsport has applied some carbon fiber on a few areas, including on that prominent rear wing which significantly boosts rear downforce.
