Giessen-based tuning specialist Leib Engineering has revealed its latest project car based on the last BMW M3 Cabriolet.

Visually, Leib confirmed that the owner wanted to keep things understated. So understated that even the original M3 badges have been removed, while the factory alloys have made way for the 19-inch Y-spoke wheels usually found on the 1 Series M Coupe.

Things are a different matter under the bonnet with the introduction of a supercharger. Fitment of G-Power’s SK II CS compressor package, which comprises a belt-driven ASA T1- 523 unit, an additional fuel pump, optimized ECU software, sports air filters and a carbon/stainless induction air track, sees output from the 4.0-litre V8 engine rise from 309 kW (414 hp) and 400 Nm of torque to 449 kW (610 hp) and 590 Nm. A stainless steel exhaust with HJS 100-cell sports catalytic converters and variable valve was also added.

Finally, the chassis was upgraded with a stainless steel KW DDC coilover kit, which allows the driver to choose between Comfort, Sport and Sport+ modes via the M button on the steering wheel.
