Sounds good, depending on the offset.
But listen, man. All this stuff is just my opinion. I had 16x8.5 wheels and I thought their diameter looked too small for the S13's wheels wells. Hell, I thing 17's are just barely big enough for the wheel wells, but I still like 17's because they have much better tire choices than 16's and cheaper tires than 18's.
But it's my opinion that hatches looks best with 17's in the front and 18's in the back. Kinda like Corvette fitment... lol... For me, it has to do with the rear of the car being bigger, taller higher off the ground than the front. Hatches do this, but not so much on coupes.
I think 17's look great under front fenders for either the coupe or hatch. 17's look great under coupe rear fenders too. But under hatch rear's? 18's completely blow 17's away, IMO. But I feel the 18's are a tab too big for hatch front's. 18 all around look good on coupes though.
Really study those setups on
