1977 Porsche 934.5 Coupe

The 2nd of 10 934.5's built, Peter Gregg purchased the car for the 1977 IMSA and Trans Am seasons. The car was disqualified from the 1977 IMSA race at Road Atlanta due to an illegal bumper designed by crew chief Jack Atkinson. Gregg would focus on the SCCA Trans Am series with the car and win 8 of 10 races and the Championship in 1977. During the season, crew chief Jack Atkinson and the Brumos Racing crew would modify/upgrade the car to full 935 specs and win the IMSA Mid-Ohio 3 Hours. Bruce Leven purchased the car for the 1978 season and would race it under his Bayside Disposal Racing team. Thereafter to Dennis Aase and Les Lindley raced this car.

In 1977, Porsche AG built only ten 934.5s. This car is the second one produced and was purchased by Peter Gregg. The car arrived in Jacksonville sometime in February or March 1977, requiring much preparation by the Brumos team for the car's debut at the April Road Atlanta IMSA race. After being disqualified by IMSSA at Road Atlanta, Peter Gregg decided to campaign the 934.5 in the SCCA Trans-Am series. During the 1977 Trans-Am season, bodywork from a 935 was used on this 934.5 in various configurations. Peter Gregg won the 1977 Trans-Am Championship series with this car. However, the results were challenged, and after months of debate, the FIA overturned Gregg's championship. Undaunted by this protest, however, Porsche produced a poster commemorating the 'true' winner of the 1977 SCCA Championship - Peter Gregg.

On 2/22/77, Peter Gregg and Jack Atkinson, Brumo's Crew Chief, flew to Zuffenhausen and purchased this 934.5 and a single turbo 935. The 934.5 arrived in Jacksonville, Florida, in February or March of 1977. It required preparation by Brumos before debuting at the Road Atlanta IMSA race. It was disqualified by IMSA, so Peter Gregg decided to campaign the car in the Trans Am racing series. The 935 purchased was not raced in 1977; it did, however, set an IMSA record at Daytona. During the 1977 SCCA Trans-Am season, the bodywork from the 935 would be used on the 934.5 in various configurations.

Peter Gregg, won the 1977 SCCA Trans-AM Championship with this car. However, Canadian Ludwig Heimrath protested the championship, and eventually, the FIA ruled in Heimrath's favor. Porsche, however, produced a poster commemorating Peter Gregg's championship.

In 1978, Peter Gregg sold it to Bruce Leven of Bayside Disposal. #59 is repainted in Bayside livery and re-numbered to #85. It was raced for only two seasons - 1977 and 1978. It was sold to two other Southern California owners and remained in storage, as an unaltered time capsule, out of public view for 25 years before it was acquired by the present owner.

The Brumos Porsche 934.5 was restored to exact detail as Peter Gregg raced the car by its former crew members, Jack Atkinson and Paul Willison of Willison Werkstatt, Inc, Lake Park, Florida.

The six-cylinder 3.0-liter engine produced 590 horsepower.
