For Sale: 1981 Porsche 935 K3 Kremer

Submitted by on August 7, 2009

Another classic machine for sale. From Graber Sportgarage

“The last of the K3 built by the Kremers Brothers. Featuring a 3.0 lt flat 6-cylinder engine with twin turbochargers.  Extensive race history including the 24 Hours of Le Mans 1981 and 1982 and Monza 1000 km entries. Receipts for more than 200’000.- CHF including a complete engine rebuild . The car features FIA papers and full detailed period history.

The FIA’s Group 5 regulations introduced in 1976 meant that for the first time, grand touring and prototype cars had separate championships. The GT series was for both Group 5 and Group 4 cars. Although Porsche had already announced the 934 for customers who wanted to contest group 4, the 935 was initially only envisioned for the works team. Even so in the hands of both works and customers it was to prove an unprecedented success, winning 150 major races before the regulations effectively banned it from international competition in 1984. In 1977 the factory developed a new car with twin KKK turbochargers and certain aerodynamic modifications, while 1978 brought a 10 cm lowered and lengthened chassis (Moby Dick) which won the Silverstone 6 hours and easily outpaced both Porsche and Renault prototypes at Le Mans.

The fact that these cars were not on sale to customer teams decided several teams to develop their own variations. One such was the Cologne based Kremer Brothers. During the glory years of the 935 Kremer cars managed to win every major international endurance race including the Daytona and Le Mans 24 hours, and the Nurburgring 6 hours.

The car we offer here chassis number 935 K3 010 0020, was the twentieth and last. It was built in 1981 and first appeared at the 1981 Le Mans 24 hours in the hands of Don and Bill Whittington and Ted Field. Although it qualified 6th, the first of the Group 5 cars, it was sidelined after three hours by engine failure. The Kremer brothers then decided to enter the car for the German DRM (Deutsche Rennsport Meisterschaft) series with driver “John Winter”, (real name Louis Krages). Here the best result was a fine 3rd place at the GP for Tourenwagen at the Nurburgring. Things looked up in 1982 when 020 took second overall at the Monza 1000km in April driven by Rolf Stommelen and Ted Field. At that year’s Le Mans 24 hours a practice accident by Edgar Doren left the car 19th on the grid before engine trouble brought about an early retirement.

The last outing for 020 was at the Norisring where ”John Winter” could only manage 13th overall. After that the car was sold to the Collection Rosso Bianco in Aschaffenburg, where it remained until in 1999 it was sold to an enthusiast in Florida and sold back to Europe, to the current owner in 2004.

Once in Europe further work was undertaken to return the car to full original specification. It was then entered in the 2006 Old Timer Grand Prix, and the 2007 Classic Endurance Race at Monza.

The engine has been completely rebuilt in 2007. Chassis number 020 comes complete with FIA papers and a fully detailed history file compiled by marque specialist Ulrich Trispel that details all the competitions prior to 1982. It also comes with receipts for over CHF 200’000 for work completed since it returned from the USA.

This is a well-known car with a continuous history that has been fastidiously rebuilt to give the next owner real long-term competition success and satisfaction.”
