Glad that you are enjoying the new diff - BMW really should have gone with a 4.10 diff in the 6MT from the factory given the relatively tall gearing of the 6MT box..

The laws of physics are such that in reality changing the diff does not actually equate to a consistent gain like what adding power to your engine does, but there is no doubting that a higher final drive ratio certainly affects the butt dyno...
