Abstract:
1. An apparatus for controlling the down force on the drive wheels on the rear end of a vehicle, comprising: a) an airfoil being disposed on the rear end of the vehicle; b) a rotatable pivot shaft disposed on said airfoil mounted thereon; c) an intermediate linkage having first and second ends, said first end of said intermediate linkage adapted for pivotal connection to said rotatable pivot shaft, wherein said intermediate linkage is downwardly disposed; d) a balance lever having first and second ends, said first end of said balance lever adapted for pivotal connection to said second end of said intermediate linkage, wherein said balance lever is downwardly disposed; e) a bob weight being suspended from said second end of said balance lever, wherein said bob weight moves rearward when the vehicle accelerates, wherein said bob weight moves forward when the vehicle deaccelerates; and, f) a fulcrum disposed between said first and second ends of said balance lever, wherein said fulcrum contacts said balance lever when the vehicle accelerates so that said airfoil rotates so as to increase down force on the rear of the vehicle.
