My guess is you want to lower your car and maybe your vehicle is heavier dude to a big stereo system or having 4 people ride with you and you want to make sure your car keeps its handling characteristics as well as doesn't bottom out or bounce.
Pfadt springs are designed to lower the vehicle and boost factory performance in turns as well as straight line. You will keep your shock travel as well as not bottom out with Pfadt springs.
If that doesn't answer your question please let me know
Hotchkis sent me the load rates for their lowering springs. I want to compare with the other options.
