I am currently running my winter setup, OEM 18x7 ET50 with Conti DWS06 225/40. I'm lowered on H&R with Koni Yellows. I want a flush fitment, or something pretty close. What size spacers could I use without having any rubbing issues? Fenders are rolled. I was thinking 10MM F and 15MM R. Any thoughts? @minsanity what do you think???
