since noone has answered your thread i will contribute, my old r33 had:
front: 18x8 (32 offset)
rear: 18x9 (45 offset)
the fitment was good but pretty tight to the suspension on both the front and rear. I would think that a 10 offset on the rear would see the rim hit the suspension and brakes, can't be sure tho, sorry.
