Many different types of cars compete in the classes with a fairly equal chance of success.

The homebuilt race car has a place in CSR or DSR as much as one of the manufactured “ready to drive” cars.

New technology and innovation are often rewarded with success, yet older cars can still win, as proven by 2000 SCCA Runoffs DSR winner Al Beasley Jr. using a 1986 Decker (pictured in yellow on the left).

DSR sports racers are ...
  • Stohr DSRPowered by up to 190 horsepower,
  • Yet weighing as little as 750 pounds,
  • Utilizing racing slicks, diffusers, and wings for traction,

Kropp chassis

Sports racers are essentially what most people picture when they think of open wheel formula race cars, except that sports racers are covered with fiberglass/composite or aluminum bodywork. Car chassis (the structural framework for the cars) commonly consist of tube frame, space frame, and monocoque.

The class rules allow for a wide choice of engines, with each choice having its own displacement limit and associated car weight requirement.

Power plants commonly used include motorcycle (2 or 4 stroke), snowmobile, or small automobile engines. Although, even engines can be custom built.
