German tuner Leib Engineering has followed up its impressive M3 GT500 and 3 Series GT300 aftermarket packages with something special for the 1 Series M Coupe. The baby M was one of the most popular cars to tune of the past twelve months, its 3.0-liter twin turbo straight-six being a particular area of interest with pimpsmiths. Leib is no different and offers two stages of tune. The first increases output from 335hp and 332lb-ft of torque to 400 hp and 369 lb-ft via a remapped ECU and a Supersprint flap exhaust system controlled by the car's M-button on the steering wheel.

By removing the electronic limiter, top speed now stands at 191 mph. 500 hp and 442 lb-ft of torque is the second option for 1M owners, with this added power coming from larger turbos, a bigger air intake and revised cooling and exhaust packages. On the styling front, Leib was instructed to replace the Valencia orange paintwork with a matte grey wrap. It then added a carbon-fiber trunk lid spoiler, Alpha-N tail diffusor, and a set of 20-inch Bavaria BC5 Concave alloys powder-coated in baby blue paired with a Bilstein suspension.
