PINEPRO-Pine Car Derby Pre-Cut Car- Aerodynamic Wafer. This is a great item because it is lean with an aerodynamic body style and works well with PineCar flat weights. It is also rough-cut and ready-to-finish and has pre-drilled axle grooves with extended wheelbases options. This package contains one 1-1/2x7x1/4 inch wafer. Made in USA.
