325i LSD

I am going to do some researching to see if anyone has swapped out their rear differential for an LSD, going from a 3.73 to a 2.93. With any luck I can find someone that has already done it in the BMWCCA chapter in Sacramento...

I don't want to lose a lot of power, but honestly, I don't go tearing around like a NASCAR driver anyway. Fuel economy is important to me.

I would also pay a mechanic that has done it several times, just to know that it is done right...

Thanks for the information!
