9.1.1. Formula Atlantic (FA) Specifications GCR - 194
Bodywork:1. No part of the bodywork and aerodynamic devices shall exceed in height a horizontal plane 90cm(35.4”) above the ground. The safety roll bar/roll cage and the engine air box are not included inthis height restriction. Measurements are to be made as raced with driver on-board.
2. The overall maximum width of the bodywork behind the front wheels shall not exceed 130cm(51.18 inches). The maximum width of any aerodynamic device situated behind the rear wheels,including the rear wing, shall not exceed 110cm (43.307 inches).
3. The bodywork ahead of the front wheels may be extended to an overall maximum width of 150cm(59.055 inches) provided it does not extend beyond the outside of the front tires. Flexible ormovable aerodynamic skirts are prohibited. No part of the body or suspended part of the car shallextend more than 1cm (0.394 inches) below the horizontal plane forming the bottom of the tub orchassis floor (both static or in motion).
4. Any part of the bodywork ahead of the front wheels exceeding an overall width of 110cm (43.307inches) shall not extend above the height of the front wheel rims.
5. Any specific part of the car which has an aerodynamic influence on the stability of the vehicleshall be mounted on the entirely sprung part of the car and shall be firmly fixed while the car is inmotion. Aerodynamic devices, including wings and end plates, shall not extend to the rear morethan one meter (39.4 inches) from the centerline of the rear wheel hubs.
6. Neither the safety roll bar nor any of the units associated with the functioning of the engine ortransmission shall have an aerodynamic effect by creating a vertical thrust.
7. The leading edge of an airfoil fixed to the front of the car shall not be sharp. Minimum radius --0.5cm (0.2 inches).
