F8X M3/M4 CF Drive shaft mod

[Altaran]

Does it feel significantly different than stock?

It revs better. It is almost like changing from a dual mass to a single mass flywheel. Not quite as significant but noticeable.

I also had a clunck with the old driveshaft, probably due to worn bearings. It's gone now.

Okay perfect I’m ready for the group buy.
EthanolTurbo Hi! 🥰

Just let me know when you guys need driveshafts. It's a great mod as long as the measurements are done right.

Figured I'd give an update.

I've now put over 1000 kilometers on my CF shaft and have zero issues. No track yet, still waiting on a Dyno tune before that.

I'm in. I already have a driveshaft ready to go!

You mean the CUNTaking?

Will let you guys know as soon as I can. I have to fix the misfires that popped up last time I drove the car. My brother is most likely going to throw the driveshaft in and test it since I don't have time currently.

Any news yet? I hope this works out.

Let me know if there is still an issue. I can call Powertrain Industries and let them know their referral didn't work out. Not sure if Powertrain Industries has any relationship other than they used to work for them.

Any updates?

Should have an update in a week or so.

While we’re waiting, does anyone have both outer diameter measurements handy? I’d like to do the math to quantify the stiffness benefit.

I unfortunately did my 6-speed swap too early, I have a F8x driveshaft sitting in my garage with no one to install it. Waiting for feedback, might have to take a trip to LA soon.
