I can't help thinking that as long as the Solstices can shove a 285 (is that right Donnie? Memory foggy) tire underneath, isn't this whole discussion academic? Similar power to weight ratio + enormous tires == Solstice FTW, as far as I can tell anyway.
--Karl, interested because there's a Solstice model in A Stock too...and I can only get a 245/275 tire combo on the S2000...
Well, the Solstice can get up to even a 295 on there, apparently, though I think it's a bit taller and thus probably not the tire to have in CS, anyway (might help the gearing on the AS car?). But it probably isn't easy to do. The 285 is pretty easy, at least for a Hoosier. The reason nobody is screaming much now, though, is that the Solstice that won CS and CSL was on 245 Kumhos. That said, I personally think the reason that worked was that it was relatively cold and the 245 got heat in it better, whereas the 285 never got to operating temperature. Will it when the weather is warmer? I gotta think so. Where is the breaking point, though? I dunno.
While I think the GXP is probably competitive in AS, I still have zero reason to believe it's the car to have. Falkner apparently kicked some butt in the Frank's car on the Tour practice course, but I don't know that everyone in AS even ran, and other AS folks that saw his run said it didn't appear to be anything to be concerned about. Jury is still out, obviously.
It's worth noting that the day before Nationals for CS, the guy that did end up winning was visiting with Hoosier and very serious about getting a set of 285 Hoosiers, even though he's a Kumho contract driver. That obviously didn't happen, but he didn't have a lot of confidence in his tire going in, that's for sure.
Last year at the Pro at Mineral Wells, I overheated my 225 Hoosiers on the '99 Miata during my *second* afternoon run. I can only imagine 245 *anything* on a heavier Solstice would have been gone as quickly, if not faster. But I'll bet you could have at least gotten two runs in a Solstice on 285's.
