Walter Brun’s organisation developed its own Porsche 962 variants in conjunction with John Thompson’s TC Prototypes company, employing Formula 1 experience and techniques, their aluminium honeycomb/carbon composite chassis proving stiffer than the standard factory aluminium fabrications. Brun Motorsport often ran as many as three cars in each event, sometimes each in their own individual sponsorship livery. Brun won the FIA World Sports Prototype Championship of Teams in 1986 – beating both the rival Joest and Porsche factory teams. Brun Porsches contested every Le Mans 24-Hour race from 1984-1991, finishing 2nd overall in 1986. Brun race engines were built and maintained by Porsche Motorsport in Stuttgart.
