NASCAR logo. The National Association for Stock Car Auto Racing (NASCAR) makes and enforces numerous rules and regulations that transcend all racing series.. NASCAR issues a different rule book for each racing series; however, rule books are published exclusively for NASCAR members and are not made available to the public. [1]
In sports car racing, balance of performance (BoP) is a regulation and mechanism that maintains parity between competing vehicles by adjusting the limits and parameters of a vehicle such as horsepower, weight, engine management, and aerodynamics to prevent a single manufacturer from becoming dominant in a racing class or series.
The new rules eliminated the asymmetrical bodies on cars, which had run rampant since the 1998 Taurus launch (and intensified by the final years of the Generation 4 car). However, almost all advantages of using one car over another have been nullified. NASCAR requires all CoTs to conform to common body templates, regardless of make and model.
The restrictor plate limits air into the engine, reducing horsepower and speed at these tracks from 230-240 mph to 195-200 mph. At these races, in addition to the restrictor plate, there are a variety of other technical rules and regulations to keep the cars stable and on the track.
The series featured Ford Mustangs, Chevrolet Camaros, AMC Javelins, Mercury Cougars and Pontiac Trans Ams. [1] Several Grand American cars were former SCCA Trans-Am cars, extensively modified to meet the NASCAR safety rules and weight limits.
NASCAR eventually adopted a restrictor plate to limit top speeds for the 7.0L engine as teams switched to small-block 358 cu in (5.9 L) engines. NASCAR edited the rules in a way that they hoped would make the cars safer and more equal, so the race series would be more a test of the drivers, rather than a test of car technology. [21]
NASCAR's new weight rules required a new lighter weight chassis (although in practice existing Car of Tomorrow chassis remained compatible). Those changes came with a hefty price, as they increased the cost per car by $500,000 for the season.
The minimum weight of each car is 1,335 kilograms (2,943 lb) including the driver and excluding the fuel, with a minimum load of 725 kg over the front axle. The minimum weight for the driver is 95 kg and includes the driver dressed in a full racing suit the seat and seat mountings and any ballast needed to meet the minimum weight.
