This car is one of ten cars built by Porsche in 1977 exclusively for the North American IMSA and Trans-Am series. Chassis number 930-770-0958 was the eighth customer delivery and was campaigned by Canadian Ludwigh Heimrath in both IMSA and Trans-Am. Heimrath won the 1977 Trans-Am Series championship after successfully protesting Peter Gregg for illegally using parts from a 935.
The car was subsequently converted into a 935 and raced by Heimrath from 1978 to 1980. It was retired at the end of the 1980 season and parked in a warehouse in Toronto, Canada.
Porschehaus acquired the bare chassis and a container of related bits and pieces in 1995. The car was rebuilt over a period of five years to the original factory specs as delivered to Heimrath. Sold to Jim and Lawrence in April of 1996.
The car was test driven for the first time at the 2004 Mont-Tremblant Legend event and the 2006 Wine Country Classic.Also photographed at :
