ThNks for all the help, guys. So now I need to find the optimal height, and see if I can match it, without going into a bad aero zone or safety zone. I guess I didn't need to ask, I should have been able to figure it out myself.
If anyone tries it, let me know, or has any results or ideas, I'd like to hear. When I try it, I will post any results. The soonest it will be is this coming spring. New 18s for the rear, and hopefully new 17s for the front.
Again, thanks for the input everybody
