A recalibration of the speedo isnt required the idea of changing the speedo gear is to make the speedo accurate for the gearbox, diff ratio, tyre combination that is being run in the car.
ohk, i thought u's were taling bout the gears behind the actuall speedo. Is there a calculator or sumthin so i can tell what gear i should be usin? How do i tell what gear im usin at the moment?
Yeah on most cars who knows what they are running. Try finding a pink 19 tooth you think the 25 tooth light blue one is hard I looked all over the place for one.
Wont be long and chris wont have a problem finding a 25 tooth one
I do have a collection of a few speedo gears here in my travels in looking for a 19 tooth I collected every one I found.
