Thought I might as well post an update to this thread.

I'm now running a set of NT-01's in stock sizes on my original 91' rims. They're simply amazing compared to my old GY's (which I'm now running as street tires only on 5 spokes). It's a completely different car, I'm having to re-learn how to drive it. I've run them in 3 events now and get faster every run. For pressures I've worked my way down to 33 front and 29 rear (hot).

I realize these are NOT drag slicks, but I'll have to take them to the track. They've made a word of difference in the way the car launches.

I also further tweaked my alignment. I was getting some outside wear on my passenger tires. When I originally setup my alignment, I did it with no weight in the passenger seat. I think this was a mistake, since I have a passenger 95% of the time. So, with weight in the driver & passenger seats I now have the following alignment specs:

FRONT
Camber: -1.9 -2.0
Caster: 5.5 5.5 (need to re-check my print out, but this is close)
Toe in: 0 0

REAR
Camber: -1.3 -1.3
Toe in: 1/8 total (1/16 per wheel)

Car feels very neutral and predictable here. Can't wait until the next event!
