Does anybody know of a company that can make custom final drive ratios for the JDM B16a Y1 transmission from an Integra XSi? I've called ATI, Gear Speed Inc., and Kaaz, and Quaife but none of them offer this service. I am wanting a final drive of 3.7 or lower 2.5 being the lowest.

I do not want to have a whole lot of acceleration because the motor being in such a light car will already offer that. I am swapping on larger wheels, going from 185 60r 14s to 215 40R 17s, to somewhat "lower" my final drive.
Oh, the final drive on my factory transmission is 4.4. The companies I listed above offer higher numbers for faster acceleration, but remember that you lose top speed. Can't have both, unless...
