Got one of the first Dinan diff's installed in October, and haven't had any problems (knock on wood). This is the best 'bang for the buck' mod for quicker acceleration you can get IMO.

Thanks to everyone who responded so far. I had a Dinan Diff in my E39 M5. Never had a problem and it definetely made a huge Diff-erence (pun intended.)

Here is what I have so far from both the M5 and M6 board:

8 Dinan installed , 2 have issues.
2 Evosport installed, 0 have issues.

Anyone else have a 3.91 installed?
