NASCAR uses restrictor plates. They are a thin aluminum plate that fits between the carb and manifold. It has holes bored in it to whatever size NASCAR dictates and is the easiest way to restrict the amount of fuel to the motor. Usually only used at Daytona and Talladega.

Same concept for fuel injection cars except it is just referred to as a "restrictor" and it fits in the throttle body.

"Awards" weight can be placed anywhere on the car but is typically bolted to the passenger-side floor board.
