Kremer K4 (1981)
Using factory 935/78 ‘Moby Dick’ plans, Kremer built their own version. In doing so they modified the body to their own design to include more downforce.
Only two cars were built in K4 specification. Bob Wollek drove the first car to win the Porsche Cup in 1981. Later this car was sold to John Fitzpatrick Racing and driven by John Fitzpatrick and David Hobbs to many successes in the IMSA series. The car was further modified by AIR with intakes on top of the front fenders and numerous detail differences. This helped the car win the Riverside 6-Hours and four more races in 1982.1. K4/01 It was raced up until the 1984 Sebring 12-Hours were it placed 6th overall.
The second car was built for Interscope by was never raced due to overheating issues in testing.
