    There are several spreadsheets posted on this site that should help you find a final gear ratio that works for you.

    The one on the first few pages of my build is an example. Final drive ratio opionions vary. Some think 4.5:1, others 6.0:1, etc.

    Personal experience with a 'Busa with 14/63 and 31 inch tall tires is that 4.5:1 (63 divided by 14) is too high. My car easily went 50 + in 1st gear. My final drive is now 6.94:1 but I have yet to drive the car with the new setup.
