The cars are divided into two groups: GT500 and GT300 (cars with no more than 500 and 300 horsepower (374 and 224 kW), respectively). These power outputs are capped via the use of intake restrictors although some heavier cars are given allowances to run larger restrictors to maintain parity.In order to ensure maximum excitement, both GT500 and GT300 groups are run at the same time although points are awarded separately for each group.
