anyone know of a way to decide the teeth on a speedo gear once you change rear gears.Im looking to change the rear gears in my car and want to know the best want to know if there is a formula to decide the speedo gears teeth without the cost of trail and error.Thanks[S
 
Most transmission shops can help you. That what I did, tell them the rearend ratio, transmission you're using and tire diameter they have a formula and will sell you the gear you'll need.
