SEMA 2008. Studie AG BMW Z4 M Coupe in the Yokohama Tires Booth.

The exterior conversion began with genuine BMW Motorsport front and rear bumpers, flared fenders and side skirts constructed in dry carbon and weighing almost nothing. A dry carbon rear wing from SARD (Sigma Automotive Racing Development) in Japan was also added. The bright paintwork was inspired by the endurance racers seen at the Ring but are a custom mix since nothing was available off the shelf.

Super-lightweight, forged magnesium, BBS RE wheels measure 19x8.5" front and 19x9.5" rear. They are dressed in 255/30 front and 275/40-19 rear Yokohama Advan Sport tires for superior grip on the track. Behind the wheels are Brembo six-piston calipers clamping 355mm rotors up front, with four-piston calipers and 345mm rotors at the rear.
