Well, I have loved the grip of the yoko's for some time now. Indeed, about three years now. THat said, as I bought another set of tires, i decided to step out of the box a little. I just bought a set of R888's in stock sizes. should be here in a few days. I'll be at a bunch of track events during the next few weeks and let you know what I think. personally, the higher tread wear rating is exciting.
