Drag racing is a type of motor racing that involves automobiles and motorcycles. They compete, most of the time, two vehicles against each other. The course starts with both vehicles standing at a stop. It is a straight course which measures a common distance of ¼ of a mile. Electronic timing and speed sensing systems have been in place to record these races since the 1960's. .
Super gas and super stock cars are two common cars used in drag racing. Super gas vehicle entries run on a 9.90% index. These vehicles are primarily full bodied cars and street roadsters. No dragsters or altered cars are permitted in super gas racing. Competitors often use electric aids to run as close to the class standard without going under and to consistently hit the 9.90 index. Super stock entries look like ordinary everyday passenger vehicles, but in fact, they are highly modified racing cars. These vehicles are classified using their factory shipping weight and horsepower. In super stock races, the vehicles compete on indexes. .
Bracket racing is a form of drag racing that is known is the "grassroots" of drag racing. This type of racing allows a wider variety of course to race against each other; whereas traditional drag racing separates cars and other vehicles in a wide variety of classes based on weight and power. Bracket racing classes are much simpler. These races accommodate any vehicle with a safety inspection, as well as a technical one. This type of racing started as an alternative which didn't involve money and also served as a fair playing field; it also allows almost anyone to race. This type of racing places more influence on driver and his/ her abilities rather than the vehicle itself. The goal of bracket racing is to place premium consistency on the driver, not on the vehicle/ raw speed. This makes victory much less dependent on winnings of large money, but more dependent on mechanical and driving skill.
