3.63 Differential - $600 Shipped
Open differential purchased new directly from BMW. Has 16K miles on it, like new (open diffs really dont wear out) Had input shaft modified to fit 325. Should fit E90/1/2 325/328/330 manual transmission cars. (your shop may have to swap input flanges with your stock diff) Gives the car some great pull in all gears, and makes 6th gear more useful.
I really need to get this thing out of the way.. its a great deal!
