How much spring rattle do you get on the road over bumps?Got 350lb springs and short Billys , to be track car.Went for a test up the street.

You'd have to be close to getting air to have the spring leave the perch enough to rattle. You could always add helper springs if concerned about that. I have never heard "spring rattle", though I hear the spherical bearings in camber plates rattling after not too many miles, particularly at low speeds. Between side exhaust noise, door rattle and all the other noises a track car makes I don't believe I could hear spring rattle even it if it was there. On spring rates, I am using 425 lb up front and 350 lb IT springs (Ireland) in rear with billy sports, hollow IE 22mm bar up front and solid 22mm IE bar in back on a 2000 lb car. Adjustable rear subframe with 2.9 camber in front and 2.1 in rear.
