Here we lay out the project and explain how to order your own parts and why doing everything at once was the best choice for this build. Follow my Instagram @high.spool.teacher. Please like comment share and subscribe! Thank you 🙏🏻

[@supraboy82]

looking to do this swap also! thanks for the video! info is lacking on this. i have an opportunity to buy a rear subframe with the goodies atm. i guess the bucket seat will have to wait.

Thanks for the video! I just subscribed. I’m looking to do the same as I’m upgrading turbos. I want to be able to put the power down 👍🏽

[@blrn54]

Thats the best way to upgrade the 335i rear end.

[@Highspoolteacher]

I think so too!

[@andreagate542]

Great info!!!! do you mind me asking how much you paid for the M3 subframe, diff and driveshaft.. I believe you said you were in Ontario I am from Toronto🙏🏾

[@ssswdon]

Were those the same ratio? If so did you have to code the new ratio for MHD or tunerpro?

[@johnutah9638]

Good video. I have installed the same m3 diff, stub shafts and am down to only having to get the driveshaft modified. I talked to a reputable driveline shop in my area and they have significant strength concerns about removing the stock flange and welding it onto the m3 dct piece. Do you have any pics/videos of your modified driveshaft? Thanks.

[@Highspoolteacher]

Hey John, sorry but unfortunately I was too impatient when it got to that part of the process and I just threw it in the car without taking pictures. The weld is fusion welded, so it has to be taken apart with a smaller shaft inserted inside of the driveshaft to give the new flange something to weld to. In other words, you have to insert a smaller diameter pipe in the end of the cut shaft to strengthen the flange.

So, how did it turn out?

Where did you say you ordered this from??

[@holeshot895]

How did you make out? I'm in Ottawa. I have an E90 335i, I am currently doing a full DCT swap on it. It's a full caged race car I run at Mosport and CMP. Hit me up if you're in the area. M

[@Highspoolteacher]

Good to know! So far it’s been a great swap except I’m getting lots of drivetrain vibrations. The donor car was written off from a front end collision so I think the diff is fine. I believe my driveshaft isn’t balanced correctly

Where did you find an m3 rear subframe?

[@Highspoolteacher]

I bought it from a dismantler on eBay

335i diff 2.56 M3 diff 3.15

[@Highspoolteacher]

335i diff 3.08 M3 diff 3.15 The 2.56 you are referring to doesn’t come on a 335i. It’s possible that it is the DCT diff for a 335IS, but I don’t know
