YFCM Carbon Driveshaft

[Epoustouflant]

I measured 52 13/16" (52.8125") from the front where the flange meets the guibo to the rear where the CV joint meets the front of the differential mount. These measuring points are circled in red in the attached photos.

So...its .7" longer if using an M3 guibo. 1" if using a non-M guibo.

.7" longer sounds trivial (that's what she said) but I'm sure it adds quite a bit of cost. I wonder if there is a thicker guibo that would bolt on and reduce the lengthening needed.

Guys,

Looking at this here - are we sure it's just 0.7 inches in length? Looking to validate, YFCM has interest.

Depends on which guibo is used. With an M3 guibo - its .7", with a non-M its 1".

For anyone interested, I have 3 units available for delivery right now:

• 1x 420G 6spd
• 2x SMG2

You can order here.

This got developed and tested btw! It's on pre-order basis for now right here.

Just to be clear...which version driveshaft is this? v2 or v4? These have been fully tested and there are absolutely 0 issues with balancing and vibration?

Edit: Just noticed the OG is banned. LOL...welp!!!

To be fair, users on this forum have reported the YFCM driveshafts are excellent. OP was banned because of drama between him.and the admins.

These are the ones that vibrate and had issues. It's detailed in this thread I think.

This is what is mentioned in the original post.

"For those that are unaware, MFactory / YCW Engineering / Michael Yip private labeled YFCM's carbon driveshafts while pretending he owned the patents. Many issues arose from the delivery on a "new" V3 version, which turns out to be a poorly retro-engineered version of the V2 with balancing, vibration and probable ungluing issues."

So who is Michael Yip?

Are these made by Mfactory?

The link to the history is missing.

I thought by the pics these looked like Mfactory ones.... Is Yip just having Mfactory make them for him?

I'm so confused.


First of all, Mfactory doesn't have one employee lol.

Second of all, IDK who this Michael Yip dude even is, I've always worked with Dave, here in the US.

Mfactory own Syncrotech, Infinitude, YCM, and others, not to mention they are the main distributer for Swift Springs. They aren't some small Tawain company run by a single individual as Euroconnex claims... IDK where he even got that from.

All of these leaves me with more questions than answers.

[9kracing]

Yes - he private labels Exedy parts for most drivetrain components he brands as his. It's unclear whether this was his plan or not for final drive gears.

I just read through this thread, and this ^ is total bullshit. All Mfacorty parts are sourced through their subsidiary Syncrotech, who has been in business for decades.

It sounds to me like Matt got upset when they wouldn't give him multiple driveshafts for free when he got more group buyer participants than expected.

I've never had a problem with Matt and was sorry to see him get banned, but there's a LOT of misinformation in this thread.

it's too bad you didn't catch this thread thread before he got banned

on the old forum YCM and Mfactory both had accounts and would routinely accuse each other of making generic underdeveloped cf driveshafts that wouldn't work. i assume euroconnex laid the matter to rest after doing his "curating" process

you could always message him on euroconnex but he controls the narrative much better on his own platforms, imo its a big reason he didn't last long here

I’m confused too…the one thing I got out of all of this is you really can’t trust these driveshafts…my opinion. Too many issues. Can’t be on V4 because V1 to 3 didn’t work…versioning assumes working part in my mind.

Just saw pics of one that basically came apart on an E92 M3 which, in my mind, confirms that these are not a quality product.

I agree with what you are saying and if the oe F8X CF DS plan/conversion works out for us that's the way to go or just stick to OE.
