Nope. For a 450hp build, I'd consider reusing the M3 diff. But with real power and huge sticky tires we wanted a little more strength and better ability to choose a different final drive and limited slip.
So...we ditched the BMW diff and used a combination of Ford parts. Terry will cover all the details and show what it took. There are some tight space constraints under the car that made us do a little more work than we normally do when swapping IRS diffs.
