Do Ford springs if you want a budget spring, otherwise eibach pros.... if you do get the BBKs get the progressive rates, not the standard rates.
Mine was dropped roughly 1.5"s and i wish i went lower. The HEIGHT is GREAT for street-able driving, but i feel every bump and pebble.
Honestly, my subframes made the largest difference on cornering. I also suggest a wider wheel all the way around (315s on all 4s, maybe?)
the BBKs wont give you what you are looking for... coming from someone who drives a BBK-equiped car everday, you can trust my judgement.
I like the stance okay... id prefer a little lower, but i also have smaller wheels... so... i could do bigger wheels to help fill the wheel-wells.
for budget springs, once again, i suggest ford springs.
