In 1973 Porsche was very interested in participating in the World Sportscar Championship and to do it needed an adequate car to be registered in FIA Group 4 reserved for cars derived from series production.

So it was that Porsche engineers made the 911 Carrera RSR, a competition variant of the 911 Carrera RS 2.7 presented in 1972.

Compared to the standard version, the RSR had been equipped with four ventilated disc brakes, new stiffened sports suspension and widened wheel arches to accommodate the new sports tires.

A 308 hp 2.8 Hexacylinder Boxer was installed as the engine, managed by a five-speed manual gearbox and combined with rear-wheel drive.

Brought into the race, the car proved extremely performance, managing to conquer two FIA Cup for GT Cars in 1974 and 1975, becoming one of Porsche's most iconic racing cars.

His fame is still well rooted in the admirers of the German company and in 2011 the DP Motors tuner from Overath decided to be inspired by it to make a high-performance 1974 911 Carrera.

Called DP11 RS, it had been updated with a new carbon fiber body kit and new Plexiglas components to replace the windows and the glass windshield.

The original engine was changed to a 326 bhp 3.6 Hexacylinder boxer with 381 Nm of torque derived from a Carrera RS Clubspor equipped with an exhaust system from an original RSR and new disc brakes, limited slip differential and new ones were introduced alloy wheels made by Fuchs wrapped in competition tires.

The cockpit was also lightened with new carbon fiber inserts and a safety roll bar was installed to increase the torsional rigidity of the steel frame and sports seats derived from a Porsche 935.

Thanks to the reduced weight to 870 kg and the higher power engine, the DP11 can boast performances almost similar to those of the 911 RSR.
