    Angle of rear spring plate in degrees and ride height??

    I suspect this has been asked and answered, but I can't find what I'm looking for, so:

    In setting the rear spring plates, does anyone know what a 1 degree change in the static spring plate angle translates into in body height with the weighted car on it's tires? TIA

    1 degree gives a little more than 5/16" of extra ride height using my calculator, but that difference number will be a little different if your car is flying high at factory ride height. The angle of the springplate will be steeper and so the effective spring rate will be greater and the effective swing arm shorter.
