can anyone help out with a progression of a rear suspension setup? i mean i'm going to to a spring relo, and possibly a small tub job. but at what step should i do this, the end result needs to be a hd road combo, and just thought i'd throw on a sway bar and might get the springs strengthend (de arch and add 1) and add a swaybar. but for the race handling, is there a better (cost effectivness in mind too) idea?? like 4link + coilvers?? i dont want air anything either. any sggestions?
