The formula to compete in Crosslé 9S sports-racing cars; in either continuation or original specification. Races are typically 2 x 20 minutes.
The Crosslé Racing Drivers' Club was formed to promote and race the Crosslé 9S sports-racing car, and in 2016 the CRDC joined the grids of Bernie's V8s and SR> with the 750 Motor Club.
The Crosslé 9S sports-racing car - as raced in period by Grand Prix drivers John Watson and Peter Gethin - is one of the revered marques along with Lotus, Chevron, Lola and Abarth who competed in the golden age of two-litre sports car racing in Europe. Conceived in 1966 for the International two-litre Group Six regulations, the 9S enjoyed considerable success on the race circuits of the continent and the USA, and to this day they are front-runners in historic racing on both sides of the Atlantic.
Crosslé drivers enjoyed success at English circuits such as Brands Hatch and Snetterton, competing against the more well-known teams such as Lotus and Brabham, however it was in the States that the Crosslé reputation for outstanding qualities of strength, safety and success were really established.
Now the 9S is available as a 'late run' series with a choice of modern production engines for road or competition use, built by the same factory on the original 1960s jigs and to the same traditional Crosslé standards. Crosslé Racing Drivers' Club cars run to the following specification:
Chassis and bodywork must be as per the manufacturer's original specification. The minimum weight excluding driver is 510kg.
2-litre Ford twin-cam Zetec, built and sealed by Paul Dunnell and running twin Weber carburettors - producing in excess of 230bhp. Period specification Lotus Twin-Cams and BMW M10 engines are also permitted.
All cars use the classic five-speed Hewland Mk9 gearbox, ratios are free.
Any tyre from the current MSA Blue Book list 1A or 1B, such as the Avon CR500 or ACB10, plus Dunlop 'L' or 'M' section tyres.
