Speedo correction help.

Recommended Posts

Hey guys, fitted my 9" with 3.5 gears, and changed the speedo drive to suit (3.55 with FMX) but speedo is still 10kays too fast. Reads 60 and GPS reads 50km/h.

This will be out because my wheels and tyres were changed, and the new boots are taller.

My question is, which way should I go to correct the discrepancy,  more teeth on the gear drive, or less.??  

It will be way easier and heaps cheaper to change the speedo gear than buy new tyres......

 

It's a cable drive in an XB, so Jaycar speedo correction boxes are a not an option. 

 

Cheers

Bear.
