BMW South Africa is releasing 25 special edition M3's that boast a 30hp and 20nm increase over stock. Each unit will have the M Dual Clutch Transmission as part of the standard specification and rely heavily on performance-enhancing parts from AC Schnitzer, among them the exhaust pipe, intake manifold and revised engine management system. http://www.m3post.com/forums/showthread.php?t=415322
