I just got an 07 GXP. I want to put some stock x8's on the rear but this is my girlfriends daily so i wondered if I could find a full set of take offs and run the x8's on all 4 for summer, probably stick with the Eagle F1s that are on it, I know that would work just fine. My real question is with the x7s on all 4 corners in the winter with some snow tires, Blizzaks or simmilar, would there be any handling side efects or would I be fine?
