I am running 12.5 in the front with the OE sizes. You are welcome to try the set I have on too if we meet up. I have more (less, i dont know) camber. On sharp bumps I rub a little bit. Then again I am lowered slightly as well.
If you want a set of 12.5mm I have brand new from Turner I haven't opened and not sure if I will use. Caddy looks like he has a few sets kicking around too. lol
