Anyone corded a set of R888's yet? Ive done 6 track days on my shaved R888's and they seem to be getting stickier. Not much tread left on the tires, less than 1/32nd. How much further do you think I can take it without hitting the cords? My worry is that I cord the tires on the track and then have to drive them home that way. Not a good thing to do since I do not have a way to bring an extra set of tires with me to the track.
