I've looked around as well, the cheapest way I went was putting Sonata EF strut assemblies on, it lowered my fronts 1.5"-1.75", and my rears about .75"
It's impossible to escape the natural "boat-ness" of this though, but my suspension bushings are all screwed, hopefully replacing those should stiffen my car up better. I'd suggest you check those as well
I'm trying to find a set of tasteful, simplistic 5 spoke rims, I want to run 20" rear and 18-19" front with heavier offset and roll the fronts. So far I might have to get TSW Rivages or Enkei EV5's. It's hard to find something with class
