tire and gear calculator

It seams that some of the most common questions seem to be about what tire and gear ratio to use on our trucks. I made a tire and gear calculator on excel that will give hard data for different combinations. All fields are editable and I used Marlin Crawlers site to find transmission ratios. The defaults are for an R151f.

Here you go.

- 1987 4Runner, 1KZ-te turbo diesel, R-151F tranny, SAS, dual ultimate marlin T-cases, custom front/rear bumpers, slowly collecting SR5 options in maroon.
- RC4WD 1:10 scale crawler, yota axles, R2 2 speed enclosed dig transmission, 4 runner body by 'BigBird'
