Distinguished by a power to weight ratio improvement of 10%, the previous generation E46 CSL (Coupe, Sport, Lightweight) was slated as a purists' club-racer version of the standard M3 with many features intended to increase performance and reduce weight. Visually, it was differentiated by its' carbon fiber roof, front and rear bumper fascias with integrated carbon-fiber reinforced plastic (CFP) splitters, special 19-inch wheels and a decklid with integrated rear spoiler.Unfortunately, BMW has decided to cancel plans for the E92 M3 CSL, however, that hasn't stopped California based tuner, Vorsteiner, from creating their own interpretation. With emphasis on the visual aspects, Vorsteiner has created a body kit which consists of a dry carbon fiber front add-on spoiler, rear diffuser with 3 integrated aero fins and a new replacement boot lid with a built in lip spoiler. Also, Vorsteiner has added a titanium performance exhaust system that weighs only 7.9 kg (17.3 lbs) versus the factory system that weighs 25.6 kg (56.3lbs). Vorsteiner has also developed a 5 spoke wheel design named V-302 series. This forged 3 piece aluminum wheel is available in 20x8.5J and 20x10J – front and rear respectively. For the interior, Vorsteiner offers a full carbon fiber interior trim kit to complement the carbon fiber exterior of the vehicle.
