Drivers in the Brick Rigs International Championship for Stock Car Auto Racing use custom-built race cars with bodywork heavily based on everyday roadgoing cars. These use a standard stock car frame, a collaboration between Car Crusher and CL86. The bodies are based off of workshop cars.
Around the time NASCAR cars became more modified, traditional stock car racing broke off from the group and kept doing what it had always done. This fictional series is a blend of the two types, with more liberty for different and more accurate body styles, linked to the now-defunct Community Street Stock series. The fifth generation cars take a more contemporary form, with uniform bodies and multiple series of different body styles.
