Ekkehard Zimmermann designed and built his first prototype with a body completely constructed from a polyester material between 1960 and 1962, based on a shortened VW Beetle chassis nicknamed the “Dingo”. When Zimmermann had the car inspected by the West German state agency to have to new body approved, the authorities were very impressed with its quality and execution. A decade after the “Dingo” was approved for public roadways, he decided to go into business for himself and founded his company Design + Plastic, more commonly known simply as DP or DP Motorsports.
DP Motorsport gained international recognition in the late 1970s when they formed a relationship supplying and manufacturing parts for the Kremer brothers racing team from Cologne, Germany. DP’s work with the Kremer brothers began while the team was campaigning a pair of 911S and 911T models in international circuit racing. A rim manufacturer released a new wheel that was one inch wider than the factory for the rear axle, but the wheel and tire combo protruded from the body. DP was commissioned to design a wider fender flare to accommodate the wider wheels and tires, and the relationship between the racing team and DP Motorsport began to build. Porsche Kremer team recognized the desire for some of the non-factory-backed teams to run the slant-nose style hood and fenders and larger rear wing to gain the aerodynamic advantage of the Porsche factory 935 entires. Group 5 racing allowed for aerodynamic changes, provided that the body shell remains stock. In 1975, DP designed and produced the bodywork for the Porsche Kremer K1 endurance GT prototype. The K1’s spectacular performance and superb workmanship led to speculations that it was in fact a Porsche factory entry in disguise. Together Kremer and DP built a number of internationally successful racing cars, most notably the 24 Hours of Le Mans-winning Kremer K3.
While DP’s presence grew in the racing community, so did their popularity in the aftermarket sector, and road-going Porsches could often be found with DP components. DP capitalized on this and began offering complete conversion bodywork kits for 911s and 928s. The DP 935 modifications include the slant-nose front hood and fenders with pop-up headlights, unique side skirts and wide rear fenders, 935-style rear spoiler, and rear bumper.
This example began life as a 1986 US specification 911 Turbo before being converted to the US Version DP 935 II bodywork in 1988. The front bumper and integrated spoiler forgo the more outrageous 935-type bumper with integrated headlights for a more factory 930S-look bumper, featuring a lower oil-cooler scoop and brake cooling ducts while retaining the factory fog lamps. Inside, the factory seats have been replaced with Recaro Competition bucket seats trimmed in black leather with contrasting white piping with the DP logo embroidered on the headrests, a set of white gauges take the place of the factory instruments and include a 10,000 rpm tachometer and 200 mph speedometer, while a custom center console houses aircraft gauges for cylinder head temperatures, exhaust gas temperature and charge air pressure and an HKS electronic fuel injection controller. The stock steering wheel was replaced with a smaller diameter RUF steering wheel.
A 412 horsepower, twin-plug 3.4-liter engine was built by Deman Motorsports of Blauvelt, NY in 2003 with ported and polished high flow cylinder heads, Carillo connecting rods, Group B camshafts, DP intercooler, a K29 turbocharger, and DP twin outlet stainless steel muffler. For additional cooling, an upgraded DP copper fin tube front oil cooler was installed with braided lines with AN fittings. The stock fuel tank was replaced with a 27-gallon Fuel-Safe fuel cell. Braking is handled by a Brembo GTP brake system with 340mm rotors and Brembo brake calipers with stainless brake lines. Bilstein coil-over suspension with 270 lb springs at the front and 370 lb springs and adjustable sway bars were installed to control the 911s handling through the corners. The 17″ Zuffenhaus 3-piece Fuchs wheels fill out the wheel wells much more than the original 15″ DP wheels and have massive, grippy 235/40 and 315/45 Nitto NT-01 tires mounted to put the power to the ground.
DP Motorsports has become a name synonymous with the success of the Kremer brothers race cars and the high standard of quality that has been a defining element of all of their components since the company’s inception. With DP’s iconic 935 style bodywork paired with high-level components and build quality, this 930 has all of the performance capabilities to back up its menacing styling.
