The 1960’s and 1970’s were undoubtedly among the greatest years for international sports car racing in history with large fields and a host of the cars, many powered by highly modified American V8 engines. Among the most successful cars of this era was the Lola T70 with Chevrolet or Ford V8 engines, while major opposition came from the Porsche 917 and various Ferrari models.
Many of these adrenalin-pumping cars have been entered for the Castrol Edge races for Pre-1974 International Sports Racing Prototypes at the Passion for Speed classic meeting at Zwartkops Raceway on January 28.
“Castrol has been involved in motor racing virtually since its inception more than 100 years ago and the arrival of this premium lubricant brand in South Africa was a spin-off of Castrol’s support for Malcolm Campbell’s world land speed record bid at Verneukpan in 1929, so Castrol premium Edge product is a natural to link with these races at Zwartkops,” explained Castrol SA’s recently appointed Public Relations and Sponsorship Manager, Nandi Canning.
Heading the entry will be three Lola T70s to be driven by Garth Waberski, Hennie Groenewald and Colin Butcher. Challenging them will be the awesome Porsche 917s of Colin Frost, Clare Vale, Rui Campos and Peter Bailey.
The special Martini Porsche of André Bezuidenhout will also be in the field.
The International Sports Prototypes will be backed by the Pre-1974 Le Mans GT cars, including the Porsche RSRs of Frans Pretorius, John Greve and Dillon Miller.
These Goliaths will also be hard-pressed to hold off the challenging Davids, mainly in the form of a quartet of track-hugging and nimble Chevron B8s and B19s.
Adding spice to the action will be three Group 5 production cars – two Camaros and Robbie Smith in a Capri.
These two Castrol Edge-sponsored events, which take place at 11:50 and 16:10, promise to be among the highlights of what is always a well-supported and exciting race day at Zwartkops.
