i was trying to find out if my speedo is right based on tire size, trans ration, diff ration, and rpm and noticed there wasnt such a calculator in our tech library. i did a little searching and found this one and think it would be a nice addition to our calculator section. http://www.kabamus.com/garage/gears.html#gearspeeddata
