Frank,
I have heard anything from 2" - 2 3/8" on left rear and up to 3 3/8" on the right rear. I don't have too much info on ride heights.
I know they try to keep the nose as low as possible.
You have to remember that the Bando cars have a go kart type set up in the front. Shocks and springs are only in the rear.
Don't know if that helps you, but I don't really have a good answer for you.
Steve
