Interesting, I know someone in NY who runs Cobras at Lime Rock and didn't think it was too big a deal. Guess I'm going to have to explore this a little more with him and with Lime Rock themselves. First thing I might try is looking up what the regs really are...
Don- yeah, you're right, I had COM confused with PDA or somebody. I had checked them out, but the NHIS dates are a little out of my summer "window of opportunity." I am going to give them another look on your advice.
And as far as tires... only have odds and ends, all for street/daily driver type vehicles. Whatcha' need? Something in a fifteeen or a seventeen for a new Cobra perhaps?
