Go with the Pro-kit... You will definitely see a nice drop that will look just right. If you want that "slammed" look, go with the Sportlines. I used to always run the Pro-kit on my cars and I think they're a great blend of drop and ride quality. They're stiff, but still manageable, and the car is still at a good stance. Low enough to make you look back as you walk away, yet high enough to get into and out of parking lots without having to worry (too much anyway)...
