3.91 DIFF .. DINAN vs. EVOSPORT
Thinking about upgrading to the 3.91 diff on my E60 M5 SMG ...
Any advantage with going with DINAN over EVOSPORT or vice versa?

Any other recommendations besides DINAN or EVOSPORT?

Any info would be greatly appreciated - thanks!!

warranty matching is pretty much the only benefit. Dinan's has reported far more issues than Evosports' also.

I am pretty close to diving in on a Dinan. As far as I've heard, the issues with the Dinan one have been fixed (the whining issue)...

I also had to have my first one swapped out. A bit of a pain, but nice to know that if there is a problem, all you need to do is drop the car at the dealer (and get your loaner) and it is addressed. No hassles.

I can't help to feel shitty everytime i take my car in for service due to this item though. They are tired of it, i'm tired of it. When does it become a little over the top? Ill obviously stick it out and do enjoy the 3.91 diff however it takes commitment and patience.

Dinan has to be hurting with this product, its no wonder that all their costs are so high! they gotta cover the 2-3 replacement diffs.
