I have a set of four Kumho V700 Victoracers 205/55R14 with about 20% life left. They were heat cycled by TireRack. They should be good for a couple of more track days. I had them on my NA for a little while in the fall. They are not slippery like the little amount of remaining tread would seem to indicate.
I will let them out of my garage to play for $50 for all four.
