    Burly 168mm LSD setup

    I have an old school BMW LSD currently installed in an E36 differential housing for sale. The LSD was fully rebuilt by Wanganstyle a few years ago for another BF.c'er and at the time was installed in a 318ti/E30 housing. I had the guts swapped to an E36 coupe/sedan housing by the premier BMW differential/Spec E30 shop in the Pacific Northwest - NorthWest Differential.

    The ratio is 3.23:1, as I said already, the diff is a 168mm small case, and the LSD itself is A LOT stronger than the E30 and E36 LSDs that tend to fail due to the design of the LSD cover. This LSD cover is a lot thicker, larger in diameter and clamped together by the ring gear bolts (see pics below).

    If anyone is entertaining a swap from a medium case diff to this small case diff, I have some axles as well that I could include. They are E36 Coupe/Sedan fitment and may fit other models. Why would you want to do this: 20lbs of weight reduction, That's why I did it. I am now going to bigger tires which means the minimum weight for my racing class goes up by 200lbs. I no longer need the weight reduction so I'm going back to a 188mm diff and a fancy aftermarket LSD. For the record, this diff survived 24,000+ miles attached to the motor in my car, making between 250 and 270whp (got stronger as the tuning got sorted) and 220-240 ft/lbs of torque.


    I am asking $400 plus shipping from Blaine, Wa 98230. The diff in the housing weighs about 65lbs, so probably 68-70lbs for shipping.
