Well, a good suspension set up is Tein S Tech springs (lowers about 1.8" front and 1.5" rear and are 30% stiffer then stock) with KYB-GR2 shocks (which are 15% stiffer then stock) and Koni Bump stops to replace your hard rubber stops... rides almost like stock once the springs are broken in...
Check out my cardomain page to see what it looks like (my exact setup)....
