23 AERODYNAMIC INFORMATION
¾
Front wing main-plane and rear lower wing are set relative to the chassis reference plane.
¾
The optimum setting for the front main-plane is –0.6° [nose up]. Any chassis rake angle will
alter this setting.
¾
Front flap inclination is intended to be the angle, relative to the chassis reference plane,
measured on top of the flap front and inside the Gurney ‘corner’.
¾
Rear top wing assembly inclination is intended to be the angle, relative to the chassis reference
plane, measured between the front of the flap, on top and the rearmost trailing edge. Any
chassis rake will affect the angle.
¾
Front and rear ride height settings are fundamental to the aerodynamic balance and ultimate
performance of the car. Pay attention to the changes between static setting and the dynamic
values, at speed, on the track.
