Petty

Ray Petty is best known as a Norton engine tuning specialist but, in late 1955, he built a his own car. It first appeared at the Boxing Day meeting at Brands Hatch in the hands of Alan Cowley and lead it's first race until Alan spun. The Petty is a slim, tidy design using a space frame chassis and is notable for it's suspension arrangement which consisted of inboard coil springs and rocker arms at the front and a de Dion rear using a transverse leaf spring. The Engine was, not surprisingly, Norton.

Alan was the primary driver through 1956, though Ray drove the car himself at the Brighton Speed Trials in September and Freddie Campbell took the wheel for the Commander Yorke 100 mile race. It doesn't appear at all in 1957 but Jeremy Menzies takes over for 1958 taking several wins in the Juniors.

 The Petty is still competing and won the Earl of March Trophy at Goodwood in 2005.
