money no object aye
hmm let see...
KYB AGX's and Eibach prokit(-1.2") Tein S.Tech(-1.4") H&R (-1.5") or B&G(-1.5") springs for the "budget" street setup ~$600
Tein NA's for the perfect street setup ~$1000
B&G coilovers for a street/track setup (this is questionable, cause theirs only like one person that even has this) ~$1200
and JIC coilovers for a high-performance street/track setup ~$1300-1500
