It seems obvious that all racing cars can not race together, that is why they are subdivided into several categories. It is possible to distinguish the following classes of racing cars: Stock class, Street Prepared class, Prepared class, Modified class, Street Touring class and Street Modified class. Stock class includes mass produced vehicles able to be used for normal street driving. Stock Category cars must compete in their showroom configuration with only minor modifications allowed such as aftermarket shocks, wheels, and tires. Then there are the Street Prepared class cars. Any and all Stock Category vehicles are eligible for Street Prepared class. One is also allowed to introduce modifications to the suspension, ignition, intake, and exhaust in order to further enhance the performance of a particular vehicle. However, no internal engine modifications are allowed, and only minor changes to the bodywork to accommodate larger wheels and tires are permitted. Another category is the Prepared class. One will find high performance, production based non-street-driven vehicles here. Cars retain their original design, structure, and drive layout. Minimum weights are specified for all cars as part of the classing structure. Steel another sort of motor vehicles is the Modified class. These vehicles are heavily modified specifically for the purposes of competition. One may see excessively altered Prepared Category vehicles as well as formulas, single-seat specials and kit cars here. The last but one category of racing cars is the Street Touring class. This is a new concept that started in 1997. This category allows sedans with a maximum displacement of 3.1L, normally aspirated. The category is for the popular street cruisers with lowered suspension, air filter systems, and wider wheels. The entire group consists of two classes; STS for street tired cars and STR for "R" compound tires. And finally comes the Street Modified class, which is very similar to the Street Touring category except that extensive drivetrain and suspension modifications are allowed here. As one can see all categories differ from one another and this classification of racing cars seems indispensable to secure equal chances and thus make the races fair.
