Cool, thank you for all that! I just sent Freddy an email to check in. I might just go with the OEM rear end with poly bushings in it (I already have a set of all of them). I also heard that I can retrofit E90/1series vented rear brakes on there with the E36 M3 calipers, which I might do if I get a hold of the guy who suppsoedly has the CAD models of them, or maybe I'll just measure it all when I have the pieces.
Cheers,
