DP Motorsport was founded in 1973 by Ekkehard Zimmermann. The abbreviation "DP" stands for Design + Plastik. In the 1970s and 80s DP Motorsport built and modified Porsche 935s that raced the 24 hours of Le Mans and other championships, aminly for the famous Kremer and Joest teams. In 1983 DP Motorsport began producing street-legal Porsche 911 / 930 based Porsche 935 replicas which at the time were very popular in the US and the Arab countries. The cars had the slantnoses, wider bodies and much more power. With Ekkehard's experience and success in racing the company was able to make street legal Porsches with serious racing-pedegree. One could take the DP 935 to the track and even win a race with it.

DP Motorsport also offered tuning and body modifications for the 928 and 944 Porsches.
