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.
