I've met Mike (and Tom) at the second Hotchkis Autocross and I can say they're all great guys to hang around. They were always willing to give me pointers even though I was fighting both myself and the traction control in the Scion when I went out. It's pretty amazing what Mike can do with his Mustang. I believe when I talked to him about it, he stated he had some pretty narrow tires on that Mustang. Last I recall they were somewhere in the 215-245mm range.
