which springs are stiffest that still maintain the factory ride height or at the maximum a drop of 3/4 inch?

Prokits, probably. Tanabe NF210 springs are only 5% stiffer than stock; just enough to account for the 1" drop.

Sweet, I'll be looking out for those. :D

With higher damping rate shocks, I'll bet they'll Handle great while still not being vulnerable to speed bumps, potholes and NJ roads in general. :D
