I'm thinking about getting these and the daily driver qualities of these tires seem good from what everyone is saying, but here's the deal. In the next year (prob how long I'll have these tires) I'll be driving to Nashville for ZCON, and Probably do at least 3 or 4 HPDE's. Has anyone really tried to push their car with these tires? How well do they work on the track new/8k/15k miles? Thanks!
