In a 04 coupe with 18 x 8.5 rims with 245/45/18 tires; what size spacers should i get for the rear so it looks flush with the body? 245/45 is the recommended for all for tired but would getting 255/45 tires for the rear help at all with that or anything else? How bout 235/45 for the front? I dont want to mod anything though if possible. Also, what brand do U guys think?
