Falken RT-215 feedback requested for track use

[htheduck]

Seeking general feedback for this tire (they came with the wheels):
-my intended application will be for primarily track use: watkins glen, ny.
-i know it was a popular autox tire choice
-all my seat time has been on street tires

just wanted to know some real experiences/characteristics of the tire pertaining to:
-heat, ability to take heat, effects of heat on lapping days
-grip? / braking? overall comments?
-edges chunking?
-sidewall characteristics under load?

Any general feedback is welcome. Thanks in advance.

slightly stiffer sidewall than the RT-615, so they react a tad quicker. They are the least tolerant of heat and get more greasy than the RT-615. Very stable when at the limit, never really chunked them. I'd run them if I had them, but there's no way I'd buy them given that there are better tires out there now, especially for track use.

I'd consider trying to sell them and buying a set of more track friendly tires. But that's just me.
