The KW Variant 3's are (for me anyways) a performance upgrade. They are 3-way adjustable (compression(low speed, high speed is a preset valving) , rebound, & height)I haven't installed them yet.... I just kinda drool over them till my wife gets mad at me for not paying any attention to her....Hahaha! My plan is to keep it about stock height during the winter and drop it an inch or so for the summer. I picked up a set of square sport 18's for a summer set up. However, there was a set of style 87's on KSL a few weeks back that I almost pulled the trigger on. Those are the same style as yours..... something about that 20" staggered set up with the 315's in the back..... I'm jealous!
