Limited Slip or Posi Rear End Question
I assume someone else has run into this. Currently my back draft cobra has a one legger BMW 3 series rear end. I was told only back draft sells something to get it to limited slip, which cost 1400. Does anyone know what other rear ends fit in there like a 5 series BMW which is sold in limited slip?

First concentrate on the E36 series cars for what you want. As mentioned I believe all E36 M3s came with limited slip. Also the cars equipped with the sports package did as well. This means you can often find a diff from a used or junked car. Lots cheaper, but you do run the risk of unknown mechanical problems. In any case a limited slip diff from the E36 (1992-1999?) series should bolt right in.
You can also search for these online and there are several vendors that can supply a rebuilt unit. But, the price is in the dealership range.
I am not too sure you will feel any difference after you install one. The open diff from Backdraft (again E36 series BMW) is pretty stout and can handle lots of power. I guess if you decide you want to leave two black stripes instead of one when you do a burnout, then a limited slip becomes important.

But from what I have been told the M3 has a rear end from a 5 series. Which would mean I could use any rear end from a 5 series as long as it was limited slip…..right?

...or if you want to be able to charge hard out of a turn and onto the straightaway on a road course rather than spin the light drive tire and go nowhere fast....:rolleyes:
If you just want to street cruise and do car shows, save your money. |
