$1000 to rework the suspension for a tire change? You gotta be kidding yourself. I've run Kuhmos, Toyos and Hoosiers and maybe changed camber, maybe not, maybe a shock setting, maybe not. I sure didn't spend any money except for the tires. I didn't run IT-7 this past year, just ITS. But I still have an IT-7 car. I didn't get a ballot, so here's my vote... open tire. Run your favorite brand. I've only been in IT for 5 years and I don't think I'm good enough yet for the tire to make much of a difference. Fun is fun, run what you brung. I mean, who cares if one guy can spend another $100 bucks on tires in this class. The guy with more money is going to change tires more often anyway, so are you going to spec the number of laps required on a set next? If you're trying to be so competitive that the tire makes that much difference, maybe you should try a higher class. The faster guys in this class are going to be faster on any tire, so why limit everyone to just one choice? What happened to free enterprise? Ricky T is fast on Hoosiers, Mike C is fast on Kuhmos, Steve S is fast on Toyos, I'm slower on any of the above but I love racing for fun and the beer is cold on Saturday night. I'm happy with choices and trying different tires for the fun of it when I can buy a new set every so often.
