traction is already going to be a big issue for you with a TT setup. I would stick with the stock gearing. I've even seen, perhaps not here but def with boosted 350z's, going to the A/T gears in a manual so they can stay in gear longer.
IMO, if you drag race, 4.08s are great if you stay N/A. Go FI and I think stock gearing is the best bet. As far as road courses go, it seems to be a 50/50 split on whether or not more aggressive gears are good.
