F8X M3/M4 CF Drive shaft mod

[EthanolTurbo]

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.

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.

Does it feel significantly different than stock?

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

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.

Little confused here, but weren't we waiting on your report not Altaran?

I'm not going to lie, I have zero confidence in this mod still.

I mean he did the exact same thing but his shop did the measurements correctly the first time, I had to get my driveshaft modified a 2nd time. I had no issues or vibrations until 80+ mph and they went back and shortened it slightly. They told me if the length is off even a tiny bit it will cause vibration.

I still have't tested out the new revision but I'm fairly confident it works fine, especially now that a counterpart in Europe has tested it for a decent amount of miles.

Understood, appreciate the explanation. I guess the real concern would be high speed based on your experience with incorrect lengths and what better place to test than Germany if driven on the bahn.

That's great news. Can you post the exact length of your cf DS? Thank you
