F8X M3/M4 CF Drive shaft mod

[x Spades x]

Just wanted to give an update...Sorry for the long wait. My E46 has a blown motor so I couldn't install the driveshaft and test it...

HOWEVER... a friend of mine that I advised about this project installed it and tested on track. Works perfectly. I give this mod a thumbs up and the green light for anyone that wants to try it.

I am also putting one in my M2, but that's for a different forum.

Which shop did he use? Manual or smg?

Yeah, would be awesome if someone could condense this 27 page thread into a single post with what you need, benefits, and shops that have successfully done the conversion.

Manual. He used Pats Drivelines but any good driveshaft shop should be able to do this.

Please. I still have one sitting I'd like to have altered to install. I didn't go with the fixed length version, which I thought was the better option…hoping I was correct

I'd still like to do this if someone could get a good source and shop especially if it's in the Atlanta GA area for me lol

Sharocks and I can help you source one.

Ok all, I'm back to working on this. Scored an LCI telescoping CF driveshaft for $200! I am planning to shorten it to work on my M2. I will also be giving my CF driveshaft to Sharocks to test on his Dinan S3R since my E46 M3 needs a new motor and uh I need to source a new one and find someone to install it properly.

Progress, right? Guys? 🫣

I’ve also got a spare e46 M3 driveshaft in San Diego right now if we’ve got motivation to knock out another..

That's great! Keep up the good work and i'll be ready too, hopefully.

Sharocks is useless, unless there is a schwarma or halal guys meal and hooka involved you'll never hear from him again

Damn...what happened to the engine?

Hah, when did you move to SD? I thought you were in the Bay. I can go grab you a non-telescoping CF driveshaft and take your donor shaft to the drive shaft shop in Garden Grove for the conversion. Or you can test my already converted CF DS.

At 252k miles it finally shit the bed, cylinder #6 has 50 psi of compression and was blowing clouds of smoke out the exhaust. Now I need a donor to swap my cams etc onto. 😮💨

This is so fucking true, but at least he is very consistent with his schwarma/hookah.

Hahahhaha yes brother that's true. He always messages me at the time I'm smoking my grape mint sheesha.

I think grape mint is what he smokes, he probably copied you. Message me on IG so I can start your driveshaft conversion.
