of cars used in straight line racing, and refers to a car that has modifications to the rear framer rails and suspension system to allow the large tires to fit under the car, but sometimes low-budget racers will simply cut the body panels of the car and allow the large tires to extend beyond the body width of the car. Cutting the body is a modification that is considered substandard and if often done to falsely make a car look like it is not built well in the hope of convincing other racers that the car is not very fast, with the hopes the other racers will offer a handicap start. Such rules are also used in legitimate drag racing as classes of cars. Small Tire race – Two cars that race with a set cars with tires smaller than or equal to 28.5 in and or equal 12.5 in of tread. This type of racing usually assumes that the rear frame rails and suspension are not radically modified. Small tires limit how much power the car can apply to the ground. There are also legally-sanctioned races that separate cars into classes based on tire size and chassis modifications. There are even entire legally sanctioned racing events limited to only small tire cars and cars that use DOT approved legal tires rather than racing slicks. Such rules are also used in legitimate drag racing as classes of cars. David versus Goliath – When a large tire car races a small tire car. A dig may refer to all participants toeing a line, aligning the front tire of the vehicles, after which all vehicles race from a stop to a prearranged point (typically a quarter-mile in the United States, but may vary by locale). A roll generally refers to a race which starts at a non-zero speed, and continues until all but one participant has stopped racing. This may be accompanied by three honks which would be analogous to a countdown. To be set out lengths is a system of handicapping that allows a perceived slower car to start their race a number of car lengths ahead and requiring the perceived faster car to catch up and pass the slower car. There are often heated negotiations to determine a fair number. This would be analogous to the bracket racing handicap start format used where one car has a head start over
