Race Car Classes


The Touring classes of T1 and T2 were created to encompass the faster cars from Showroom Stock A (SSA) and the Showroom Stock Grand Touring (SSGT) classes. These cars are essentially high performance street cars with open muffler and exhaust systems. These 120+ mph cars run in the same Southwest Division (SOWDIV) race group as AS, SSA & SSB classes.

This category includes Grand Touring¨C1 (GT-1) series based production grand touring cars which are the fastest and closest to the SCCA Pro Racing Trans Am0…3 Series cars. GT-2 through GT-5 cars get progressively lighter and less powerful. SOWDIV groups the GTs with the Production class cars in a separate race group that features a broad range of cars.


A very popular entry level production-based group of classes, Improved Touring (IT) cars are former Showroom Stock cars with limited modifications. They will range from five model years old to as old as the 1968 year models. IT cars are capable of suiting almost any racing budget with over 250 models participating. The various IT classes run together in their own SOWDIV race group.


E-Production (EP) is the fastest of the production classes with H-Production (HP) the slowest classed by performance potential. These series produced cars are allowed some performance modifications.

The Production classes of EP, FP, GP, and HP run such cars as MG Midget and Toyota MR-2.


These late model mass produced street cars compete virtually off the showroom floor with no modifications except a bolt-in roll cage and safety equipment. These cars are classed into Showroom Stock A through C (SSA, SSB, and SSC) classes based on performance potential and can¡¯t be more than five model years old. They run in the same SOWDIV race group as T1, T2, and AS.


The most popular of the sports racer category, the Spec Racer Ford (SRF) is a purpose-built road racing car with an open cockpit full fiberglass body and sealed identical motors by Roush Racing. These entry level racers run on standard radial street tires and give the feel and exhilaration of much faster cars while running in their own SOWDIV race group.


The sports racer category includes C-Sports Racer (CSR) and D-Sports Racer (DSR) which utilize a variety of chassis and engines. Like the Spec Racer Ford, they are purpose built road racing cars with open-cockpit, full fiberglass bodies and a pure racing chassis. The Shelby Can-Am (SCA) uses sealed engines to provide a level playing field. The Sports Racers and FA, FC, FF, FM all run in one large, fast SOWDIV race group.


Sports 2000 (S2) is an open cockpit, rear engined car using a two liter Ford single overhead cam engine. They run in the same race group in SOWDIV as the Sports Racers and the Formula classes of FA, FC, FF, and FM.


Formula Vee (FV) is based on the engine and chassis of the Volkswagen 1200 Beetle/Bug. On a good straight with several cars drafting together, they may exceed 120 mph.

These Formula cars are single seat open wheel racecars built to a set of detailed specifications (formula) for weight, size and engine displacement. The smallest of the formula cars, these two classes still have incredible power to weight ratios.


Formula 1000 is a new class for 2007 (FB) as introduced by the SCCA. This car will be one of the fastest, latest technology race cars on the track.


Formula 500 (F5) cars possess the smallest wheelbase and lowest center of gravity in all of SCCA competition. With wide racing slicks and up to three inches of travel on elastomer-based suspensions, they're also the quickest handling cars in Club Racing. Their snowmobile derived 500cc two-stroke engines and CVT clutching delivers over 90hp to drive a mere 800 pound total weight, including driver. This power-to-weight ratio compliments the cars' quick handling characteristics to produce lap times quicker than all but 7 or 8 SCCA classes on most circuits around the country.
The small, light-weight, and powerful formula results in one of the most fun and exciting driving experiences in club racing. Being a "restricted" class (but not Spec) limits the performance modifications allowed, keeping costs down. This also creates very equal performance levels throughout the class and results in very close and exciting racing.

Thus, one of the most defining attributes of all is the class' claim to the "Bang-for-the-Buck" crown. With new complete cars under $17k, used front-runners under $10k, new engines for $3k (lasting multiple seasons), and multiple weekends per set of tires, few classes can refute this claim.

Formula Continental (FC) and Formula Mazda (FM) are among several of the winged formula classes. They are single-seat, open wheel race cars built to detailed specifications for weight, size and engine displacement. The FC runs a stock two liter engine with about 140hp and the FM runs the Mazda rotary engines with roughly the same power. In SOWDIV, these cars run in the same race group with the Sports Racers and the Formula classes of FA, FF.


Formula Atlantic (FA) is one of several winged formula classes while the Formula Ford (FF) runs without a wing. The FA cars have unlimited 1600cc motors that average 240hp making them the fastest Formula class in SCCA Club Racing. The FF class cars run 1600cc motors with output of around 120hp. These cars may also compete in one of the SCCA Pro Racing series throughout the year. SOWDIV groups these cars along with the Sports Racers and other Formula classes a single race group in SOWDIV.


Spec Miata (SM) has been added as a National Class in SCCA Club Racing for 2006. Spec Miatas are essentially a stock 1990 through 2005 Miata with a spec racing suspension and a few other race modifications to equalize the cars. "Spec" means that all the Miata's are roughly equal and are closely monitored by SCCA tech inspectors for compliance. Spec Miata (SM) is the fastest growing race class in the U.S. and was started right here in the Southwest Division by our very own Texas Region members. Spec Miata (SM) offers some of the largest starting fields in SCCA today and is known for it's close and competitive racing.
