Congrats! I had the same purpose with the KW S/Os when I put them on my car. Loved them when I had them on the track!
Only thing to be aware of is these will wear out your dampers if you go to the track a lot. I had them on for 30 days and my dampers started to feel the effects. The biggest indicator was during high speed turns going into a front straight, the car would ever so slightly bob more than it used to and have that squishy effect.
