Square or staggered?
 

I am getting new wheels soon, so the base 18's are going to get some track rubber for autocross. I've heard from countless people out there that a square set up is the best for autocross. If I run 245's all the way around will the car act weird because the front wheels are 8" and the rears are 9"? Or should i just go 235/245 in the front and 265/275 in the rear?
