Brumos, Kremer, Gunnar Porsche, J.L. Racing, Momo and so many others all wanted to the 935 to another level. With the 3.2L and a Kugelfisher fuel injection turbo pump electronic fuel mixture would be taken to new level.
By the closing end of the (1980) 935 era The 935 wasn’t just available by Porsche any longer. If your team wanted a 935 in 1981, they would have to be special ordered. This required having Reinhold Joest or Kremer Brothers to make a car from factory parts and then further incorporating individualized customizations. Modifications were very surprising, as bolted to factory 911 frames huge plenum chambers which sat over the air-to-air intercooler.
The Porsche Factory also had its 935/78 “Moby Dick” plans given to the two tuners Joest and Kremer Brothers. Yet further modifications would then need to be used to add to aerodynamics, suspension, and airflow to the rear wing. Other changes would be changing the material specifications in the frame such as chrome molybdenum steel tubing. There were also remarkable innovations that included lowering the chassis, widening the front track and better brakes. In some cars, long-tailed body’s had both aerodynamics and ease to mechanical access from top of engine and gearbox. Tube frames where very much used to lighten the weight of the car, control body flex and roll, plus allow better places to quickly remove and replace panels on the body.
If you ever get to see a 935 in person, be sure to try to jump in and take it for a spin.
