What kind of tires does the Vette run? Hoosiers are fast, but they're also more expensive.
I looked back at your previous post again, and noticed that your biggest complaint is about tail-happi-ness. I'm curious what your alignment settings are. There's many, many things to try in order to get it under control. Rear tire pressures and shock adjustments (if you've got adjustable shocks) probably being the easiest. I have a feeling the problem probably stems from the car being mid engine and having sloppy bushings in the rear suspension. I have some Dali non-compliance toe-links, but I never got around to getting them installed because of messed-up threads in my subframe, but they wouldn't be legal in ASP anyway.
Glen "Hurricane" Hernandez is awesome. I've never ever been able to beat any time he's achieved in my car. I seem to remember one event where I was doing not-too-bad against the ASP guys, and then he jumped in my car and took like 2 seconds off my time, but he coned. So jokingly I said, "nice, but I'd like to see you do that clean." So of course, the next run, he took off another second, and didn't hit any cones at all.
My NSX really isn't in a position to be autocross at the moment. Partly because the brakes need replacement for racing use (and I'm waiting to be able to afford a big brake kit), and the other being that I gave away my old race tires and the rims they were on, leaving me only with my Kumho Ecsta Supra 712s, which are horrid for autocross. But if you'd like a co-driver, I'd be interested in that. It sounds like you're probably already pretty quick, though. I may only be able to serve as a tire warmer.
When I do get my NSX in race condition again, it won't be with autocross in mind as the top priority, so I'll probably end up doing mods that make it inelligble for ASP (like the non-compliance toe links, and a big brake kit).
I see you're a graduate of Doug Hayashi school of performance analysis.
