First of all, I'm going back through your thread and I'm learning some things now that I understand this better. I think I have the same color interior, I see your trim matches. What is the official color? Just the Schwarz (black)?

Also, In the original photo, you had an ashtray on your trim, and the one above you have the blank, is that piece swappable?

Is the split arm rest even worth doing? For manual trans guys, I suppose it can be useful but I don't really rest my arm there too often.

Im willing to do the rear subframe swap of the m3 (3.15) to my 135i DCT, so witch OBD2-USB cable is the best or are basically all the same? and what software are you using to do the TCU recode-reflash.
I know that i have to buy the M3 Gear shift stick, the part that goes under it and the center console buttons , what else do you recommend to buy? do i really need to buy the M3 Kombi gauges also?

Thanks lots

Couple points to note:
  • The 135i interior is different than the 335is interior so a bit more modification required
  • Practice doing basic coding first - NCSExpert (something like fold mirrors on lock)
  • Practice updating with same software - WinKFP
  • M3 Kombi is nice because you get the larger gear display (only applies to 135i)
  • 2.81 & 3.08 gearing works
  • If you want to try it out before fully committing you can drop in a used 3.08 differential (<$200 ebay)
I'd wait until you have practice with the coding side. Try adding the BMW performance DME flash first. That's a simple task, but exercises your understanding of using the coding software.

For those of you who have tried this swap in a e82, do the shift settings and larger gear display on the e82 cluster with the proper coding?

No. The E82 center info display is different. Physically not like the e90. I went with the e90 M3 cluster because I found one for a good price. The regular e90 cluster is physically the same setup and will adjust to large display with coding.

I'll upload photos comparing the two.

If getting a cluster you'll want to reset the VIN and Odometer. Then it'll reload relevant info from the CAS and/or FRM as if it were new. Otherwise, tamper dot. And the e90 cluster requires reshaping with a dremel. Not a big task, but takes time.

On a relative point (gws swap)...
The leather from the M3 GWS will adapt to the E82 surrounding plate. I can upload photos as well.

Are you running the stock 2.56 Dct diff?
