AERODYNAMIC INFORMATION 24
• Front wing main-plane and rear lower wing are set relative to the chassis reference
plane.
• The optimum setting for the front main-plane is -1° (minus 1°). Any chassis rake angle
will alter this setting.
• 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’.
• 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 alter this setting.
• 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 on the track.
