I believe that a lot of wheelspin problems at speed is caused by airodynamic lift, it has been proven that speeds around 160 mph the suspension will go into droop with less weight on the tires. Jim Hall ' Chaparral' figered this out around 1965 resulting in the spoiler then the adjustable spoiler while running,then the wing and adjustable wing. I wonder if we will ever catch up to that 1960's tech?
The formula 1 cars run 60-65% Rear weight and so do we on the 222 car, 288mph+ coupe. Rear engine lakesters, dragsters and funny cars probably have more.
