I wanna drop my camaro 2" with spindles. My car has 4 piston delco moraine calipers. Will these calipers directly bolt to a standard 68 camaro 2" drop spindle? Or do I have to buy a diff. type? Also, whats the trick on gettin those fronts to tuck? I was told my front setup,offset and tire/wheel size were a perfect fit. However When I hit a good dip she rubs!? DO they make a spindle that'll give me some neg. offset?
