Thread: 3.27 diff too excessive for Autocross?

    3.27 diff too excessive for Autocross?

    I have installed a 3.27-diff on a C36-engine/tranny, and I think the ratio is too much for autocrossing.

    Has anyone else tried it?

    While the accelleration is great, it seems to have too much drag to top speed.

    Should I go back to 2.87 or try a 3.07 ?

    Did you install the diff yourself? If you decide you want to go back to your old diff, let me know. I would be interested in putting this diff in my C43.
