What class would my car run in
SCCA Autocross has six major competition categories which are then broken down in classes of like cars.
The major categories are as follows:
This category is not intended for the street driven car, though a few competitors do drive their Prepared cars on the street. These cars have their interiors removed, one bucket seat, a roll cage, and extensive engine & suspension modifications. This class is comprised of 5 classes, from CP to FP plus XP, and they all run on purpose built racing slicks. This category often has SCCA Production and GT class cars in it and once again there is a noticeable increase in performance over the Street Prepared classes.
Autocross Rules/Classes
The SCCA annually publishes the Autocross Rules to classify a full range of imported and domestic sports cars, sedans, and purpose-built race cars, as well as to layout the basic rules behind Autocross competition. The Autocross Car Classifications are provided so that you may determine what types of cars are typically competing in Autocross, although there is a class for just about any vehicle. The organizers of local events are also allowed enough leeway to add classes to suit their particular requirements.
