Carbon driveshaft should be installed tomorrow. I wasn't able to use the lift I normally have access to, so that's why it took a long time. Will have a full driving impression by the end of tomorrow with luck.

Which shop? I’m in NorCal too and about to submit the parts sheet and measurements from the picture here to JRL Machine & Driveline in Petaluma. Would love to hear some results as well.

You mean the sheet that said 53.875 total length and 3.250 from one flange point to the other?


Oh I just realized it has the part numbers for the parts used too. Shoot I'll just bring it there on Monday and see what they say.

I'll let you know the shop if they said they can do it.

Anyone know a shop in Jax that can do this mod as long as I have the measurements for smg lol

Just picked up a drive shaft too to see how this is done. Have a local shop that wants to see it recommended by my shop that I trust. Worst case scenario I'll just sell the shaft to one of you to do this if I can't find a shop willing to. Got it for $200.

Are you able to get the driveshaft registered on your papers? I only have a vague understanding of how TÜV works, and what's allowed as far as custom parts and repairs/upgrades vs tuning parts that are explicitly TÜV approved.

I suppose you could get it in, since it's basically an OEM part and has a BMW part no on it, it's possible.

But that's not really an issue as the shaft is fully covered by other parts when installed.

I got stopped because my car has a big wing that catches their attention. It's in the papers, but he noticed a typo on the Airbox entry in the papers which is ridiculous. So now I am having that corrected and I should be good.

It doesn't matter which one you get. One is PreLCI (cheaper), the other is LCI. You can use a donor E46 330i driveshaft or you can splurge and buy new end pieces like I did.

Can you share the part numbers for new end flanges? I only see CVJ part number 26117841003. What about the other side that bolts to the guibo? Any other miscellaneous parts needed?

There are 2 versions of the f8x driveshaft with different lengths correct?. I guess it really doesn’t matter as the driveshaft has to be cut down regardless. A donor e46 m3 driveshaft is needed to source the flanges. Anything else?

Part number 26117855000 is 1477mm in length.
Part number 26107857629 is 1471 mm in length.

Still nobody has installed?

Soon. Should have the carbon driveshaft and carbon roof done next week.
