Depends if you have camber plates. With stock camber you would only fit 225/40r18 front and 255/35r18 rear. With camber plates set for the track you can go with 235/40r18 front after a 3~5mm front spacer is fitted. Some coilovers may need a larger spacer depending on the springs used.

When you set maximum -ve camber on the rear, the 255/35 tire will rub the fuel filler tube at full compression. So a 3mm rear spacer will reduce or solve the rubbing.

If you are really serious you may be able to fit 245/40 front and 265/35 rear. It will need fender mods, larger spacers and still have some rubbing in a couple of places.
