It doesn't show up in the pictures but the rear control arm bolt has about 1 1/2" of shims on them due to the spindles I used. I though initially that I would have to run shorter arms for exhaust clearance but I think I'm sitting really good even if I jump up to the big corvette manifolds.
With the front clip on things look pretty good. The bottom of the fender is 8 1/2 inches to the ground. My goal was about 8 to the bottom of the running board (same as my 2000 Impala).
Firewall clearance is good. I'll clearance it a little more when I build motor mounts.
