I've been running the ARK GT-F Springs for a couple weeks now, and have been very happy with them. They are about an inch lower than stock. There's a stretch of city roads on my commute that made me a little nervous about lowering, but the ARK's have performed well and haven't been too harsh. Given my roads, I wouldn't want to go any lower, but so far it hasn't been much of a sacrifice in comfort. It certainly handles the curves better.
