CSL are legendary letters for M3 fans. Like the formula applied to the Porsche
Scuderia and Lamborghini
Superleggera, CSL stood for more power and less weight. BMW
produced less than 1,400 such stripped-out track monsters in 2004, and now Reil Performance has gotten its hands on one. Reil has stripped even more weight - down from 3,050 lbs to 2,778 - with carbon fiber doors and trunklid, topped with a Porsche GT's rear wing and Plexiglas side and rear windows.
