I've decided I'm going to do this when I do the clutch on my SMG M3.

Waiting for an outcome on this. Received a DS from Ebay a couple of weeks ago.

Any updates on how it drives with the revised DS? Thanks.

Not yet. Soon. Sorry!! It's coming.

It's posted on a previous page sonewhere: $776 with parts and labor.

I just would hate to see anyone spend the money I did and have issues. By the end of this week I should be able to test the car out with the shaft.

Update: the driveshaft shop (DriveshaftPro) called me and said my driveshaft is ready for pickup. I dropped it off last week explaining the vibration issues.

Here is what they said:

"The original drawing we went off of caused the driveshaft to be too long. We shortened it by 3/8ths of an inch and rebalanced it. This should resolve any vibration issues. The CV joint wouldn't have lasted long due to this."

So whatever specs I posted above for measurements needs to be reduced by 3/8ths of an inch. 53.875 inches needs to be cut down to 53.5 inches.

Going to pick it up today on the way to Disneyland. I have to reinstall it, but it looks like OEM carbon fiber driveshafts might be back on the menu, boys. If it works without any vibration issues, I will get a quote for 5-10 of these to be done to try to get better pricing.

You get any seat time with the revised length drive shaft?

YFCM carbon fiber driveshaft checking in! Can't wait to install this along with a 3 clutch LSD w/ 4.10s.

I'm in pending it handles high revs and speeds with no issues. Would be a plus if it we had a track day review

Realistically it will take me another 2 months or so to hit the track, as I still have other things to finish to get the car ready.

Sounds good. Please let us also know what they said was the issue first go round. Thanks.

If take 2 goes well, I am down for the GB. If you still plan on offering it of course.

Good, looks like they are fixing it. This is hilarious!

But I have to wonder how much you paid? I was quoted $800 shipped and with only having to supply the carbon shaft. Maybe you can get some money back.

Hopefully they can figure it out first
