Not sure how this driveshaft has the removal process engineered into it.

All CF driveshafts so far has suffered from the vibrations at high RPM's
Ahhhh, ok, gotcha...and agreed! I'll be sure to let everyone know!

Again, I have not personally owned a CF driveshaft but have researched it quite alot. This is what I know so far.

I really want a carbon drive shaft on my car. I do believe that is a key reason why the new m4/m3 are freakishly good at putting almost advised the crank hp to the ground on dynos. I just do not want the deal with all the headaches that the current ones on the market deal with.

I found a post from Mfactory on a UK forum stating the weight is 20lbs. If i'm not mistaken the stock is 18lbs? I'm hoping one of these figures is wrong.

I assume he means see an example. It seems weird that any part would require destruction for removal.

The deal-breaker for me is that some of these companies have said weird things about deflecting the guibo since they remove the center joint.. constantly wearing the guibo for weight savings <10lbs is pretty much a no-go

I would be interested and could possible be the 6MT Ginny pig, although I feel that if I was willing to do so, there should be some incentive ($$$) for doing so.

Either way, before I am willing to do so, I want to know exactly what the weight of this drive shaft is and how much it saves over stock? Why is this ALWAYS so hard to find out? Seems like this is still not clear, even on the ones from the competitors. I mean if the main benefit is weight/mass reduction, then it should be the first thing that is advertised. At least I think so.

I personally have not owned a carbon driveshaft as I said. This is based off of what read through searches and research on the forums. Everyone has said they are almost impossible to remove resulting in destruction.

Exactly. I'm not picturing how the shaft needs to be destroyed to be removed. How was it even installed?? The ends should be Giubo and CV (or tail end converted).

If anything you might have to loosen the diff (which is still a pain in the ass) but destruction? That sounds really weird - like tolerances are off and it's fusing to the input flange or something.
