I know another member here did the 17's but I elected to go with 15 x 7 front and 15 x 8 rear. I feel like they look like they have more of a "dish" than the 17's. Tires are 215 65 15 front (like Monte SS) and 255 60 15 rear. Seems to have plenty of clearance all around at this ride height. If lowered in the rear, I'm sure I would have to trim the fender inner lip.
Also including a shot of the rears compared to the stock 14's...
