a story you might think about...

decades ago... i was out with a friend in his dodge discover motor home.. remember the one piece fiberglass ones... ....  he had gotten some 4 way shocks from san diego...  these are the shocks for motorhomes that have the coil over spring on them but with a twist..  the collars that support the coil overs are threaded sort of on the outside.. so the coil spring is trapped... it is ajustable by loosening one of the collars and letting it recenter and tightening it ... ...

it was windy on that trip... and the 4 way shocks did not help that much... until i had a thought...  lets preload them in reverse...  so they pull down...

we drove the front wheel of the motorhome up a curb...  loosend the clamps and reset them....  

then  we did the other side... ...


there were 70 mpg crosswinds coming back from vegas .. we really did not have any problem with crosswinds after that.. ...

how would that work on a circle track car...  i know that they have something like that on indy and F1 cars.. .... the  suspention would be pulled down agenst the springs to load it... when the car is at speed the aero downforce would push the car down and let the suspention work at the race level..

maybe this will help someone.. ...  

My first thought is that the motor home had regular springs in addition to the coil over ones, either leafs or coils, that supported the sprung weight. All you did was pull down against those other springs. You created a sort of sway resistance, much like a fixed end sway bar. They sell those. If you lower a race car, you lower it, there aren't other springs to work against. So, no, it won't work with a race car.
