Which class is typically faster or are they about
the same? (Do the mods allowed in STX make up for the tire disadvantage?)

In my own experience, my pax time in CSR was pretty comparable to a fully prepped RX8 with a good (as in better than me) driver at most local events.

Yeah, on index, it says we should be faster than STX, but against tour-trophy level STX guys, I never really got all that close. Some I could outdo on index, better drivers could get me on raw time.
I think it's more that CSR isn't soft, but CS (along with most of street) were given a tougher hill to climb relative to the other categories.
When you think about it, my car on hoosiers feels like it should be right about even with a proper STX car. One crap ton of grip versus lots of suspension trickery and significant help under the hood. But, the CS/CSR index isn't set at the twins level of performance necessarily, but rather is skewed a bit towards what a 370z is capable of (remember, PAX is an attempt to describe the statistical pointy end of the class, not the mean/median/mode of everybody). STX has no such animal to worry about as the new Z goes to STR and the 350 goes to STU.
As much as I hate to say it, I'm starting to buy into the idea of the 370 needs to be moved up. I would still like to actually run against one first to see it for myself, though.
