Visually Leib has fitted the Coupe with a pretty horrendous chequered plate-style matte grey foil along with a carbon fibre BMW Performance rear spoiler and Alpha-N diffuser section. A Bilstein B16 PSS10 suspension kit keeps the 1M planted, while the factory wheels have made way for a set of 10 x 20-inch
Bavaria BC5 Concave alloys, which have been painted baby blue and wrapped in 255/30 and 275/30 Yokohama Advan sports tyres.
Thankfully the Swiss company hasn’t messed the engine up. Powered by a turbocharged 3.0-litre straight-six developing 246 kW (335 hp) and 450 Nm of torque in standard form, Leib remaps the ECU software and adds a Supersprint exhaust system with adjustable flap operated via the M button, taking output to 298 kW (400 hp) and 560 Nm. If that doesn’t float your boat, the next stage involves upgraded turbochargers, a larger air intake and improved cooling, resulting in a very pleasant 373 kW (500 hp) and 600 Nm.
