The chase for points to compete at Road Atlanta for the Sports Car Club of America’s (SCCA) National
Championships at Road Atlanta began in January and ended in early September.
There are National Championships for twenty-five different classes. These race groups fall into one of six different categories:
- Production Category – There are four classes in the production category – E Production (EP), F Production (FP), G Production
(GP) and H Production (HP). These production-based vehicles are grouped according to their performance potential.
Sports cars such as the MGB, Porsche 914, Alfa Romeo Spider, MG Midget, etc., are most often associated with this category.
- Grand Touring Category – Five classes are identified as Grand Touring – they include Grand Touring 1 (GT1), Grand Touring 2
(GT2), Grand Touring 3 (GT3), Grand Touring 4 (GT4) and Grand Touring 5 (GT5).
These vehicles are also grouped according to their performance potential.
The quickest class, GT1 features cars such as the Ford Mustang and Chevrolet Corvette, while at the other end of the spectrum,
GT5 includes the Mini Cooper and Honda Civic. These vehicles are allowed a larger number of modifications than the production category.
- Showroom Stock – Four Showroom Stock categories, Showroom Stock (SSGT), Showroom Stock A (SSA), Showroom Stock B (SSB), and Showroom
Stock C (SSC), were created by the SCCA to accommodate performance street cars with a minimum amount of modifications required to race.
Changes to these vehicles are for safety purposes.
- Sports Racers – These are purpose-built closed-wheel race cars.
There are four classes within this group – Shelby Can Am (SCA), Spec Racer (SR), C Sports Racer (CSR), D Sports Racer (DSR)
and Sports 2000 (S2). Sports Racers include a variety of chassis’ which may be constructed by the competitor or a race car manufacturer.
With the exceptions of Sports 2000, which must use a 2.0-liter Ford engine and the spec racer categories (Shelby Can Am and Spec Racer),
which is tightly regulated, there is a wide range of engine and chassis options used by the teams.
- Formula Category – These are also purpose-built race cars. This category includes five classes – Formula Atlantic (FA),
Formula Continental (FC), Formula Ford (FF), Formula (F440) and Formula Vee (FV). There are a variety of rules that govern these open-wheel cars.
- American Sedan - This new division is comprised of Chevrolet Camaros, Pontiac Firebirds and Ford Mustangs. They use the production-based chassis
with modifications to the suspension and brakes.
