Re: Chassis #13R listed for sale by Kidston

The part of 13R description for sale by Kidston, " and the spoiler on the rear deck of the F1 road car deploys when the brakes are applied to move the aerodynamic centre of pressure forward to enhance braking balance with the F1’s designed 42%/ 58% static weight distribution."

is wrongly specified. In fact, the base suction as center of pressure in undertray with automatic airbrake deployed results in an increase in downforce of 100 percent and a rearward movement of the aerodynamic center of pressure of about 4 ft., which helps negate the pitch problem.
