Znod,
I think you could put in the 3.38 diff from the 545i auto into the 545i SMG/manual. I know Koala Motorsports offer the 3.38 as an option and I wouldn't be surprised if it came from the 545i auto. I also talked to Dinan and confirmed that the diff is not a limited slip, however it is equivalent to almost 60hp. Quite a lot for swapping the diffs. Here's an email that I received from Dinan about my inquiries:
"Hi Jon,
We have just released the differential for your car, and it is a huge change. By the numbers, it is the equivalent of gaining almost 60-hp! There is no limited-slip added, just a ratio change. Our retail price is $1999, and you will be charged just over 4 hours of labor. It takes Dinan about 2-3 weeks to build the part.
Thank you,
Eric Bateman"

Can anyone confirm that Dinan's 3.45 Differential is a limited-slip differential? I was told that Dinan's Differential is not a limited slip but the stock differential from a 645ci automatic. I also did some probing and koalamotorsport sells differentials with various diffferent ratios (3.15, 3.38, 3.46, 3.64 or 3.91) for the E60 and their price is $1550 shipped with the same warranty as that of Dinan. However, if you want a limited slip differential, Koala Motorsport can make one starting at $3450 depending on the ratio. If Dinan's 3.45 diff is a limited-slip, then I'm all over it, if not then I'd have to seriously consider going with koala motorsport and get the choice to choose how aggressive I want my diff to be.
Anyone know how much it would typically cost to do the install on a differential?

I've highlighted in red the different final drive ratios available for the 545/550 manual/SMG. Does 3.91 mean that is the best ratio to have?

Hollywood,
You and I should try to get some other folks for a group buy
I don't know if I want to pay Dinan's overinflated price of $2K. Koala Motorosport is selling differentials for $1500 and you get a choice of the different final drive ratios. Dinan only offers 3.45. I think I'm going to go with either 3.91 or 3.64 from Koala. Thanks for the info Znod and choi000!

Sounds like a good idea jiio. Hey is that 1500 installed? I think if I went with Dinan I would have a piece of mind to go with it too.
