Hamann managed to get their paws on a red BMW M4 Convertible and then proceeded to do what they do best. Firstly they slapped on a new set of forged wheels which are available in either black / silver, then they added their new front splitter, side sills, rear diffuser and the noticeably modified bonnet. Underneath the bonnet they have upgraded the 3.0-litre twin-turbo to produce 517 hp which is a decent 92 horsepower gain from stock. This car does look superb and I would most certainly opt for the black wheels.
