If you were the guy I met at 75-80 I love your mods. I've been thinking about them a lot, and if you switch rear gears I think you can get deep into the 12s on street tires; at least we will be able to see how the traction control handles the limits. I've only heard about one place making gears, but it shouldn't be too long.
I also think you should post a sound clip for everyone to appreciate.
