    Diff suggestions..

    I've got an M50 w. a G250 and a 4.10lsd..

    Problem being I've now got a top speed of 110mph!

    So, from what I've gathered there's quite a few diffs available in the 3.X range but I'm curious as to which one I have and which I need to locate for a direct swap.. (large vs small) case?

    I'd like to be able to do at least 125mph too.. any good gearing calcs out there?
