German tuning company Hamann is offering its own styling touches and performance upgrades for the new BMW Z4 M Roadster. Hamann has developed an aggresive body kit for the car, including a front spoiler, side skirts, and a rear spoiler on the trunk. A selection of Hamann wheels are offered, in both 19 inch and 20 inch sizes. Extra performance comes from a specially-developed exhaust system which adds an additional 15 horsepower, totaling 358 bhp in European form.
