Question about lowering my truck

[OregonNed]

I've been thinking for a while now about lowering my truck some - probably with drop springs and leaving the two inch blocks in place. With these 15" rallye wheels I can see that I am in a "danger zone" situation the way my hardware rests below the wheel rims in the back. Will drop springs make this problem worse by lowering the trailing arms further? The suspension is all courtesy of the previous owner. Thank you.
