I can calculate other gears sets but this is what i have found.
The STI looks interesting to me. Wont have shift to 5th in the 1/4 and no top end loss.
Anyone care to coment there opinions.

The gear ratio number is the nuber of rotations the input shaft makes to turn the tires one revolution.. a lower number is a higher gearing as the rear tires turn more per rotation of the input shaft.
