Don't know if Neuspeed does this with all their products, but when I first lowered my ride, I used the Race (yellow) springs. It was cool at first, but I noticed that over time the driver side got slightly lower than the passenger side. Plus it didn't lower the front as much as I wanted it to be. I wanted it flush with my tire (at the time being, they were 205/40/16's) but it still left about a two finger gap. So I sold them for a set of skunks and tokicos.
