hey guys, glad i could help, i got the info from a really helpful member on another board
As far as springs,im running stock 6cyl springs. They work pretty good from what ive seen others say, and with not much tuning they seem to be working ok for me (need to tune more, didnt get any track time after getting them on, car broke). A stiff spring like an SS actually works against the caltrac bar and ive been told can either brake the spring of the caltrac box (these are the words out of the calvert techline's mouth)
