I just put 3,9's in my vs and wondering if someone knew the right cog the the speed sensor or how to change the reading from the computer. Any advice would be helpful! I'm out about 17kmh. Reads 80 doing 60 etc..

You will need to get one of those speedo corrector kits from jaycar and wire it inline with the signal to the dash. It can be calibrated to any ratio.

so the speedo reader is electronic? i thought it was mechanical, too easy mate cheers Some original photos have not been recovered yet.
