Hi John, if anything goes you might want to look at the rear wing theory used during the can-am series, the rear wings then wern't bolted to the body of the cars they actualy went through slots in the cars and were fixed directly to the suspension, this had the effect of applying 100% of the downforce to the rear wheels rather than some of it being lost by compressing the body down onto the suspension. Just a thought if your aloud to try anything.
