Vehicle Description
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.
