E30 M3 Sport Evo
http://www.bimmers.c...full-driver.jpghttp://www.bimmers.c...driver-seat.jpghttp://www.bimmers.c...ortevo-dash.jpg In 1990, with an already successful agenda on the track, BMW introduces the Sport Evolution. The Sport is the third and final special edition
Evolution M3 and by far, the most radical of the street-going M3's. Production reaches 600 to surpass the 500 models required for homologation in Group A DTM.
While there are many specific alterations to the Sport Evo which vary from the standard M3, several modifications focus on achieving maximum competitive advantage in Touring Car racing. Rules of the time require that racing models (a) run the same engine and displacement as the homologated car and (

no sheet metal or aerodynamic aids can vary from the homologated model. For this reason, the Sport Evolution displaces 2467cc, nearing the 2500cc Group A limit. The Sport Evo is equipped with a multi-position adjustable front splitter and rear lip spoiler so that downforce can be dialed in on a per track basis. Wider fender wells allow clearance of larger 18" racing wheels.
The M3 Sport Evolution is a 4-seat, 2-door, front engine - rear wheel drive sports car.
