Diff Poll - How many installed? How Many w/Issues?

All right let's put it all together. How many have a 3.91 rear diff installed and which brand? Also if you have had a problem give specifics?

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.)

2 Evosport installed, 0 have issues.
