B Spec
A newly created segment of race cars called B-Spec targets the sub-compact market. The aim of the class is to provide (relatively) cheap access to racing, with the intention of the sanctioning bodies to maintain a single “spec” for the cars so that they can compete in any series with minimal changes.
Series produced cars, which are allowed a range of performance modifications while retaining their original design, structure and drive layout. There is no age limit, so Production includes many cars as old as 50 years and as new as current body styles. The three performance potential based classes include: E Production (EP), F Production (FP) and H Production (HP). EP is the fastest of the Production classes with HP running the slowest in the category. Several cars in the Production classes can be run in more than one class, just by changing the engine between races. Cars included in Production classes come from a diverse group ranging from the MG Midget, Turner, Fiat X1/9, Alfa Romeo Spyder, Austin Healey Sprite, and Lotus Super 7 to the BMW 325, Mazda Miata, RX-7, Nissan 240, Honda Civic, Suzuki Swift GTI and Toyota MR-2.
Super Touring® features late-model production-based vehicles with a series of modifications to their drivelines and bodywork. STU are mid-level performance cars of 3.2 liters and under. STL is a small bore tuner class for cars of 2.0 liters and under
GT cars are purpose-built, highly modified “silhouette” replicas of series-produced sports sedans. GT cars are permitted tube-frame chassis. GT-1 cars are the fastest of the category, and are the closest to the SCCA Pro Racing® Trans-Am® Series., GT-2 GT-3 and GT Lite cars get progressively lighter and less powerful. Cars include Toyota Celicas, Mazda RX-7s, Nissan 200SX, Honda Civics and Austin Mini Coopers.
The eight formula classes are all single-seat, open wheel racecars. There is incredible power to weight ratios in each class. The classes in order of fastest to slowest are: Formula Atlantic® (FA), Formula 1000 (FB), Formula SCCA® (FE), Formula Continental® (FC), Formula Mazda (FM), Formula F (FF), Formula 500 (F500) and Formula Vee® (FV). FA cars have motors that generate as much as 240hp. Motorcycle engines are the basis for the F1000 class where displacement is limited to 1000cc. The FC runs a stock 2-liter engine with about 150hp while the FF 1600 motors make around 120hp. FM utilizes a sealed Mazda rotary engine. FV is the most popular classes in SCCA. FV entries all run 1200cc stock VW engines. F500s run small displacement, two-stroke engines like snowmobiles.
There are three classes of purpose-built road racing cars with full fiberglass bodies. Underneath, these cars are pure racing machines. The power plants in these cars vary from home-built “pieces and parts” engines to sealed identical motors.
The Prototype 1 (P1) and Prototype 2 (P2) classes feature a variety of chassis including home-built, innovative designs and manufactures produced cars. The Spec Racer® Ford (SRF) is a one-design, single seat car utilizing a sealed Ford engine, built by SCCA Enterprises
American Sedan® (AS), comprised of Chevrolet Camaros, Pontiac Firebirds and Ford Mustangs, are production-based chassis with modified suspensions and brakes. Engines are carbureted 302 and 305 CID V-8s that have been balanced and blueprinted.
Spec Miata
The Spec Miata (SM) class is intended to provide the opportunity to compete in low-cost cars with limited modifications as its name shows, Spec Miata is a “specified” class. This means that the rules for allowable modifications to the car are very strict. The class intends to put drivers on a very even footing by making their cars as identical as possible.
