    Question 4.11 Diff speedo problem

    Hi guys, just wondering, I've got a 4.11 diff as opposed to the stocky 3.45 and the speedo is slightly out.. i know how to work out what speed I'm doing and everything, but just wondering what i need to do in order to rectify this and make the speedo accurate again

    Also, what advantages if any, does a 4.11 diff give over a 3.45 ?

    Cheers, snowy.

    being a vl you can calibrate the speedo with different cogs for the gearbox end of the speedo
    I tune the oldschool way fear on the passengers face and knuckle colour cant go wrong
    tabbacco is still my favorite vegetable
