dont quote me on this but i am pretty sure reccomended is at -7 from center. I mounted mine at -5 from center, and ski the park on a daily basis no problem. I also used them at my school race teams races and had no trouble at all.
I MAKE CUSTOM DIECUTS, LOTS OF COLOURS TO CHOOSE FROM AND CAN MAKE ANY SIZE YOU WANT. PM ME FOR PRICING ETC.
