Used shorter heavier springs (ie 350/250) on the Haynes I built to race for someone and it had very pronounced oversteer,it had Ginetta rear uprights that are are direct fit for the Haynes and same dims and Protech shocks with the springs as stated,just too much of a racing car for the pilot.
Cost : Little as possible.
Thanks : To those who by their generosity my build has progressed.
Its a handmade sports car not a flaming kit car !!!

No parachute require to freefall,only if you want to do it twice.
