It may be a well kept secret, but RDSport is one of the few companies that has a complete performance program for the new M3.

From the 412 HP of the R32S Power System to the 505 HP of the Tornado S conversion, nobody delivers this kind of performance but RDSport.  And, best of all,  we do it all without deviating from BMW's doctrine of high-revving naturally aspirated motors.
