15 x 8 Americans

I am most concerned about the backspace of 3.75. It sounds like 4.25 to 4.5 is a better choice for the fish's. Remember this is a 5 on 4.5 bolt pattern rim. I wonder if this b/s is designed more for a B or E body? My 14x7 has a 4" b/s and it does kick the tire out close to the outside edge. Like I said the car will set up higher than stock with the SS's or caltracs.
