I've been told that 18x8.5 wheels will fit in front and the suggested tire size would be 235/40ZR18 or 255/35ZR18. Both of these tires come in both of these sizes.
Hankook Ventus R-S3's are probably your best bang for the bucks. They are the cheapest out of all the "Extreme Performance" category tires. If you're willing to pay more, also look into the Dunlop Direzza Star Spec and Yokohama Neova AD08. I've had those Dunlops on my OEM wheels before, I went with 235/40 front and 255/35 rear instead. They worked great and lasted quite long for what I did (autox for one entire season, a few track days, and of course all those daily driven miles). Then last summer, I switched to a square setup with OEM 193M rear wheels and Yokohama Neova AD08 255/35 all around. There's no rubbing whatsoever in the front. The grip level is amazing. The wear rate on these should be similar to those Dunlops.
