Just took a peek eBay. Used carbon f8X Driveshafts seem to have gone up in price already 🤣

Awesome!

Any chance you got weights with the M3 flanges on?

I will weigh it tomorrow when it's in hand.

Update: carbon driveshaft has been successfully completed. Will be picking it up tomorrow and weighing it. I should have driving impressions in the next few days.

Pretty sure they went back to metal because cf didn’t fit with the increases emissions gears.

Either way— no danger of us snapping them 🤣

There's late model F8x CF driveshafts, for example all the CS models have a post-LCI CF driveshaft. The ones we are using are pre-LCI.

Interesting.

Back in 2015, S55's were snapping these things so BMW went back to metal driveshafts lol.

I took my DSS CF one out because it wasn't balanced correct, if anyone has this finally installed, I'd like to know who you used and if they would do it for all of us.

I pulled out the mother of all digital scales 🤣 results here - https://youtu.be/mBAH2AII5qA?si=3h9M4hH1jDjOdkTS

6.08 kg
13.4 lbs

I shared it on page 6 of this thread. There is a very noticeable difference.

[Radekxpl]

I weighed the stock driveshaft on a certified shipping scale with the result of 17.8 lbs but that was without a guibo. Didn't go with the F8x drivshaft but instead with the YFCM. The weight came in at 11.8 lbs without guibo.

Thank you for the info🙏, By any chance can you share your feedback immediate observations when you switched from stock to Yfcm driveshaft? Is there noticeable difference ?
