Does anyone have a spreadsheet that includes tire diameters to gear ratio calculations? I'm trying to figure out gearing changes to my car.
Example: I am currently running ~23" diameter slick on the back with a 901 gearbox. If I changed to a 24" or a 25", I'd like to know what approx speed change per gear would be. I have upcoming tire testing which includes different diameters and I wanted to have a preliminary idea. Just being lazy....I was hoping someone on the board had already done the work and I could steal it.... (IMG:style_emoticons/default/laugh.gif) Thanks, Bill |
