I plan on lowering the Jimmy with a 2/3 drop, but I'm NOT using blocks for the rear. What all would I need other than leafs for the rear? The problem with blocks is that I'm rebuilding the 4.3 and adding the Typhoon turbo setup with about 12-15lbs boost or so. I know for a fact that'll rip the blocks out and I'd rather go with something with a little better ride.

Also, for the front should I do sprindles or coil springs?
