Check out this thread in the Wheel/Tire forum. Very good information here from SurferGeek.

I run 315s on all 4 corners for my track set, but on different rims front to back. Had to do some mild massaging to make everything fit comfortably. Up front its all the camber (-2.5 to -3), rolled fender lips, and 5mm spacers as the used Vorshlag wheels I bought rubbed on the struts. Out back, I had to trim the fiber inner fender liner and my PHB is pretty much exactly centered. No rubs at all on my mild car.
No reason why you can't end up with the same fit by choosing the appropriate offset wheel and spacing out appropriately in the front. No reason why one couldn't end up with the same effective offsets with a square setup and spacer in the back.
