Re: Speedo calibration
Here's a good site that'll help you determine which speedo gear you need.

Re: Speedo calibration
Does anyone know if pulling out the shaft and greasing it works? I've heard that, but I'm skeptical...

Re: Speedo calibration
carry a GPS..the only ticket that I have ever had was due to my speedometer being off because of my larger tires on an S-10....the excuse didn't work!
