I was buying V710s form this guy for the Mini. He is a Kumho sponsored road racer. I just got this email from him. PM and I will forward you his info if you are interested.
I've got a good inventory of Kumho V710s - 225/45/17's. (sorry but I haven't been running the 16's) Great condition, two heat cycles, properly managed. No blemishes, blisters or flat spots - good healthy skins. Same deal as last fall. $300.00 per set plus shipping to you.
