I see that everyone is now starting to change their differentials. Is this possible to do on an Xi? Or is the only way to pull more in this aspect getting a light flywheel? :dunno:

You have to replace both front and rear diffs with the same ratio. This was common with the E30 325ix: 4.10 from auto replaces 3.91 in the manual trans cars.

the question is, are they the same diff? if Xi has a special front diff, different from the rear, this will be a $$$$$$$$$$$$ upgrade, to find new stuff.

I'm sure the front diffs will command a higher price thanks to the lower quantity of Xi cars out there.

FWIW - According to the ETK, the following ratios exists for the Xi: 3.07, 3.15, 3.23, 3.46
