The quaife if amazing. Allow for much more of the available power to be put down coming out of bends, or controllable tail out action if one desires. Best mod money one can spend. BMW really should have spec'd this car with an lsd from the factory.
Just so you know I am not concerned with the deposit, just want you to get the diff back so you can make another m135 owner as happy as I am with the quaife.
Thanks, Chris
