Got them mounted up yesterday. Initial impressions are good. Took them for a spin around the neighborhood. They have a stiff side wall, as one would expect. The grip limit is really high on these tires. Keep in mind, they were fairly cold during the test. Road noise wasn't an issue. Transistions were crisp, there's basically no slop in the tread or the sidewall, so turn-in is immediate. The plan is to autox them this coming Sun., so I'll get a better feel for their limits at that point. I probably won't track them for a while, so testing their heat range won't happen anytime soon. I'm sure Tirerack and the internet grapevine will have tons of input in the coming months. Overall, I'm happy with my purchase.
