Speedo adapter

[ward]

Hello I have a vs clubsport with a turbo 400 fitted and have now put in 4.11 diff gears, and my speedo is reading higher than what i'm doing ie around a 80klm normal is saying 130 is there an adapter I can get to fit onto the gearbox sender?
Thanks Adam

Hi
Jaycar do a kit Speedo Corrector MkII Kit - Jaycar Electronics
Im not sure if its suitable for your application
also there should be a workshop that specializes in recalibrating gauge somewhere in your part of the world...

a youtube video showing how its installed ...not a commodore related but gives you a rough idea whats involved
