D Sports Racing

Mark Jaremko, 4 time DSR National Champion

D Sports Racing is a Sports Car Club of America class for purpose-built, 'LeMans-style', closed wheel roadracing cars. It has been called the one racing category that remains unfettered by regulations that have throttled innovation elsewhere in motorsport.[1]

Usually known simply as DSR, the class began in 1968. DSR evolved from the SCCA's older H Modified class, which traces its roots back to the early 1950s. Today's DSR cars normally use a 1000cc four cylinder engine sourced from a Japanese motorcycle. Several other engines are allowed - see the SCCA Rulebook

DSR's generally weigh under 1000 lbs with the driver and make 200 bhp at 13,000rpm. The relatively low cost of the engines and some new chassis manufacturers led to an explosion in growth of the class between the years 2000 and 2008.[2] DSR's were the fastest class at the SCCA National Championship races in 2008.

A lively spot for DSR discussion can be found at the SportsRacer Technology Forum.
