Go for the st's...I wanted something that was decent for dd, but still fun when I hit up the canyons. The ST co's were it. Obviously if you've got the cash to burn, the kW3's are great, but for me, The ST coilovers fit the bill, and you'll have money left over to do bushings, exhaust, tune etc
And hit up Jurrian @
ModBargains.com for ordering, their a forum vendor and you can expect great pricing and service.
