The issue is not getting the gears, its finding someone who is willing to install them properly. The M diffy in the E9X M3 is a little finicky when it comes to tolerances in the diff.

Here's diffsonline.com page that has the ring and pinion.

You can buy a re-manufactured diff from bimmerworld.com. Here is the webpage..

Pricing seems low. I always thought Dinans were over 4 gs. I gues we have to put it on the next mod list

They're also available from Turner.

Over the years I have found in old posts it seemed nobody sorted out the problem with DCt tranny and adding shorter rear end as it would essentially overrev the car as the DCT would not "learn" that the rear end ratio had changed. So you essentially overrevved the car.

Has anyone with a DCT and dinan rear end actually made this work and how?

I have 4.10 in my e90 M from Dinan. When I got it and it depends how close you are with your dealer but I got it for 10% off and I believe Dinan sells them at 2499 plus your original diff.

Not sure if they have a policy if your diff for some reason is damaged, but I swapped mine out pretty early in the cars life once I determined if it was necessary for the car.

One of the best modifications I have done besides the SC and MONOBALL kit.

The Dinan diff is exceptional and has held up extremely well and is exactly what this car needs if you have a manual. The only part missing is the somewhat sloppy shifter in the M. Still have not decided if a SSK is worth it, but for the 4.10 it seems like (in my opinion) the shifter just feels weak and made of plastic. I guess hard to explain. Just love my TTRS shifter and how it feels when throwing it from gear to gear. Wish I could put this in the M.

If you are considering it..do it well worth the $$ and won't regret the purchase.

The power in 1-3 is fantastic and has added good low end response. Great for track and spirited driving. Can be a bit rough at times in traffic though if a DD.

PM me if you want to talk more. If you are in New England area I would be great to meet up so you could get a feel of it.
