In summary: the base compound of the Falken FK-451 tires use the same compound as the Azenis Sports, but the FK-451s are available in many more sizes, and are even cheaper ($110 each for 245/40-17 at VulcanTire). Some people are now buying them, shaved, for autocross.
Anybody know where you can get tires shaved, or buy them shaved, around here?
