yeah, they are both 16x8's. fronts will fit on back and vise versa, but i think that with the rears, they scrub up front at full lock, which is why they are different.

The fronts have a 16mm outer stance to keep the track width the same as the rear of the car. The wheel mount surfaces of a thirdgen in stock form are narrower on the fronts than the rear faces.
