Mfactory just rebranding products? E9X M3 S65 V8 carbon fiber V2 driveshaft actually YFCM

[Sticky]

Companies rebranding or private labeling products happens all the time. There is a difference though when a company claims to engineer and design products they sell when that engineering and design actually takes place by somebody else.

That appears to be what Mfactory was doing with the V2 carbon fiber driveshaft. They also latter offered a V3 and it seems this was a much lower quality piece likely meaning they sourced it from someone other than YFCM:

I finally received the authentic "V2" carbon driveshaft. This was actually patented & manufactured by YFCM all along.

MFactory was nothing more than a private label'er - no engineering, nothing.

The comparison with the V3 I received last year is brutal.
No glued balancing weights.
The self-locking flange with much more refined machining for lightness.
The winded carbon filament with signature yellow braid over the golf-club pasted tube.
Considering the machined flanged and smaller diameter tube, I'm also anticipating the V2 to be lighter than the V3.

BimmerBoost actually purchased a V1 carbon fiber driveshaft for the E92 M3 project car but MFactory recommended we sell it and get the V2. BimmerBoost never purchased another driveshaft from MFactory.

It seems if you want the real deal with higher quality for your E9X M3, you can just go straight to YFCM.

In 6 weeks since this saga started - we were able to find, source and validate the actual patent holder & manufacturer of the authentic "V2" carbon fiber driveshaft for the E9X M3.

YFCM Composites & M. Lee

I received my DCT authentic driveshaft today & unboxed it tonight. I couldn't wait to show you guys.

First Impressions
---
The machining and overall craftsmanship is light years ahead of the Mickey-Mouse Factory V3 carbon fiber driveshaft.

Balancing weights; what are those?
---
There are no glued balancing weights anywhere. The only protruding piece is a rivet on the CV flange side.

I emailed M. Lee to clarify whether this is used for balancing, or to rivet the CV flange in place.

The signature carbon work
---
The carbon work is a work of art: it's evident the winding method of YFCM is much more researched than the pasting method of the golf club tubing of the V3.

The yellow filament, the puzzle-like weave shape in some sections, and how it all comes together is further evidence this is a thoroughly engineered product.

I Thought it was a parent company thing, like with the coilovers.

yeah I thought they even stated that in one of their posts the same thing? maybe not though.


That driveshaft in the post is a thing of beauty, that's for sure.

Mfactory contacte me and it's only fair to share their side of the story.

That's YCW, easy to mix up the two. YFCM is a 3rd party company created by a former employee of the company that made the V1 CF driveshafts for MFactory/YCW.

Interested to hear MFactory/YCW's side of things.

Sorry I've lagged on posting it. I've had a lot on my plate lately.

Hope all is well. Interesting to hear their side when you can.
