I am curious what coil-over spring rates people are using in their Chassisworks front clips for street duty? I have a 67 with Chassisworks street machine clip and sway bar, 550 lb. coils on single adjustable shocks set on the middle setting and running a LS1... When I first ordered the clip I was going to run a small block but decided to go ls instead, I figure chassisworks recommended the 550 lb springs for the added weight of the sb. Now after putting a few hundred miles on the car with no change in ride quality I think it's too rough for the street and wanted to see what other people with experience with this are using.
