I have had just about every combo posted above and my current combo seems to work best with the 3800# SS springs,NO SNUBBER,Rancho 9 way adjustable shocks. It hooks with slicks and slips with MT ET streets.I used Caltracs with mono-leafs and they worked very well but the springs wore out in one season of street/strip use. I turn a 1.49 short time the my current shock/spring package Gus
