dp Motorsport, a German company located in Overath-Immekeppel, who started operating in 1973 decided to transform a Porsche 911 from the same year into a lightweight machine through the usage of carbon and numerous other upgrades.
The rear-engined 911 received what the company calls the dp11 RS 2011 bodykit composed from carbon components such as a front bumper and hood, fenders, doors, rear fender flares, rear bumper and rear spoiler plus a set of Plexiglas windows.
The 1973 Porsche 911 upgraded by dp Motorsport has also received lightweight lamp lenses and taillight lamp holders, carbon fiber underride protection, a carbon roof panel and a green heated windscreen.
The 3.6-litre Boxer engine rated at 310 HP (228 kW) powering the 1973 Porsche 911 has been linked to a 50-mm PMO carburetor with open air filters and a G-50 Gearbox plus the car now features a limited slip differential and a new braking system originating from the 964 model but adjusted for the 911-G-Model.
This 1973 Porsche 911 sits on 15 inch Fuchs wheels coupled with 225/50-15 and 345/35-15 tires while at the interior the list of enhancements includes bucket seats, black Alcantara, a welded safety cage, and a sports steering wheel.
All these changes helped the original 911, which weights between 1,080 to 1335 Kg (depending on equipment) to be brought down to 870 Kg.
