Fall Line CF Driveshaft

Just saw this on iND's Flickr. What do you guys think? Worth it? No pricing yet but asking more from a performance perspective. F8x M cars went this direction...

Do they have them for DCT cars?

From what I've read the stock driveshaft isn't all that heavy (25-30lbs) so from a rotational mass weight savings stand point it's not worth it.

It will probably clean up the slop in the 2 peice system and allow better launches because of the stored energy properties though.

Ya, about 30lbs isn't bad at all, but like you said, launch could be improved, and we can run like 4,000 lb ft of torque through this puppy

I am not sure if this is universal or 6MT-specific, hopefully iND will post soon!

I have one I got on my car from the Driveshaft shop, think they only make it for manual trans right now.
It only saved like 3 pounds, does seem to launch a little better and since its 1 piece it did take out alot of the clunk. From DS it was 1400, not sure what this one will be.

Thanks for the feedback squartus. Do you happen to have any dragstrip or vbox runs pre and post driveshaft? I'd be curious to know if there was a measurable time improvement

Sorry no I dont, I have actually been waiting on the weather to clear so I can hit the dragstrip for my first time.
Was going by the before and after hard launches I was doing on the same street. Seemed to keep traction a tad better 1-3rd, I know its suppose to deliver the stored power in the shaft over a longer period of time since it twists more than a steel shaft.
But without real before and after testing It could of been all in my head or road could of been less dirty etc. Deff got rid of alot of the drivetrain clunk though, like when you let off gas in first and so on. You can actually twist the stock shaft with your hand and make it clunk.

^ But the trouble you had to go through to to get it working was a bit much(technically I saw it as you helping DSS to develop the product as it was not ready when you bought the item)

If Fall Line's is completely bolt on and don't need to use some sort of an adhesive that isn't included, I think the case would be more compelling.

*Crosses fingers for DCT option that is not outrageously expensive*

I hope so too man, but the M tax is still quite heavy... We will see! I'm glad high end products are still being developed for our platform, at the least.

Does this require the massive aluminum adapter that the DSS driveshaft uses?
