Dave/Gav,
The Cobra classes have trophies from 1st to 3rd, the others i..e Daytona/SC540/GT40/Mustang have only one.
The bulk of the Cobra's will mixed between classes 2/3/4/5.
There are a lot of Windsor/Cleveland based Cobra's running around on Radials
or R spec tyres. The SF Committee decided to split the older Ford's from the
modern Coyote/Modular/LS/Toyota as it was felt there was too much of an
advantage for the modern motors.
FYO, in the last 5 years there has only been 2 Turbo/SC cars in the top
10!!!!! AND IN 2009 ONE OF THEM WAS A GIRL
