Speedometer Gear Calculator up at GTSparkplugs.com

Here is the link to the simple Speedometer Calculator. It is a simple program that will help get you the right speedometer gear. You will need to know a few things such as Tire Diameter, Rear End Ratio, Speedometer Info, Transmission Gear Tooth Count. But after that it is simple!

Made a couple of minor changes and updated the text so you can understand how to use it. If anyone finds a change or wants a new feature then let me know. I was thinking of graphing the error by going up and down one tooth but not sure if useful.
