I honestly wouldnt worry about a final drive till you start getting closer to 12s. Are you running slicks? If not, Maybe get some 22inch M/T slicks. I ran those on my hatch running 11.0 on a stock LS tranny at 403hp. My buddy with a EK coupe ran 10.9 on the same set of slicks with a stock B16 tranny.

You always want to get your traction under control before you start worrying about different gears. if you change gear settings when you have no traction, then get traction, It could slow you down.
