Hello. Looking for more rear rake on my 70 vert. I rebuilt the entire rear suspension a few years ago. Added cc501 coils with a 1” billet spacer, car sits much better but still not enough rear rake. I spent big bucks on Bilstein shocks and I like the ride, don’t want to ruin it with air shocks. I see taller spacers for sale but not sure this is a safe way to achieve rear lift. Any opinions? Also I think the body mounts are original, thinking maybe I should replace those first?
