AFCO has a chart on their website (and on Speedway) to determine the correct amount of travel the coilovers should have based on the installed height. Bilstein is a quality unit, but if the valving on the shock is wrong, the length of stroke too short, or the spring rate too high they will not give a good ride or good handling........
