Mine work fine on the street. Just left a slight amount of clearance between the caltracs and leaf springs. Can’t really hear any suspension noise over my exhaust.
I have run both the SS springs with adjustable snubber and caltracs with stock 6 leaf springs at the track on the street. Both set-ups 60' the same but the caltracs ride much nicer and handle better on the street on my mid 11 second street car.
