Saleen 18x9 wheel fitment

I think you would clear with 3/4 more space, mine are 9s up front also (ghey) and they rub at full turn, I just learned how to turn like a school bus and I'm good now
 
Picking up 17x9 SC, and 17x10's tomorrow. Suspension is completely stock. Looks like I need to 'flip the quad shocks' or get rid of them. I've dug through threads can't find much more info here. Any pointers?
