1984 Fabcar 935/84

After 1980, a customer wanting one of the potent 935 derivatives could go to a company like Fabcar, Joest or Kremer to built up racecar around Porsche-sourced components and design. In America, Fabcar was built several such cars and the 935/84 was the very last version that incorporated all the successful features of the preceding models.

Dave Klym at Fabcar was responsible for the sole 935/84 which was built for Bob Akin Motor Racing. Traits of the new body included a Kremer K4 nose with NACA ducts on the front fenders and a double-window long tail rear end. The original was fabricated in aluminum and when it was done with testing a final fiberglass unit was made.

The actual chassis was sourced from the wreckage of Derek Bell’s 935L.Klym worked to revise the suspension pick-up points by utilizing the Kremer K3 front setup and a copy of the Moby Dick rear suspension. Through redesign of layout nearly 100 lbs were taken off the aeroquip lines in the chassis.

The car was finished in time for the 1983 Dayonta 3 Hour Finale and placed second overall behind the March 83G. Later the car contested the Daytona 24 Hours, Sebring 12 Hours, Road Atlanta 500 kms, Riverside 6 Hours and Lime Rock 1 Hour with limited results.

Not long after being raced, the new GTP regulations opened the door for Akin to move onto the Porsche 962 platform.
