Given the standard push rod rocker suspension;
What would be the best bump stop to add progressive rate to compensate for compression from new aero forces?
More specifically I have 3" of travel (exposed shaft at droop) on my shock using 1600 lb/in spring, 200 lb preload, with 1-1/2 in bump stop of unknown properties. The car is bottoming out with 3-1/2 in ride height. I don't want to raise the car any more and stiffer springs are not available.
