hehe, I run STS2...will be in SM2 if I go ahead with the t25 turbo project I'm working on...so I'll chime in.

Miatas are going to be faster in SM2...its just how it works, unless you really want to spend the money, or your just really, really go.

I put a low end turbo or S/C setup, get some wide ass 13x8 rims, full race tires, throw some good shocks, springs, new mount/bumpstops and a nasty front sway, an alignment, and then do some bracing and LSD and my car would be extremely competitive locally in SM2, and thats about 3-4 grand total in the car. This is assuming I'm building it to be a street car as well, b/c you can build an SM2 miata thats just for auto-x a lot cheaper, but it wouldn't be very nice or very streetable.

The miata is good, but its not unbeatable, but you shouldn't be expecting to jump into a steet modified class your first season and beat them.

STS2, yeah, its possible.
