Drive shaft issues

[Goosey]

Whats the perceived wisdom of stock driveshaft coping with 830bhp set up. I spent a ton of cash importing a QA1 CF shaft but i get a really bad knocking and vibration when full power and 6k revs. I m going to try and check the set up but I may need to go back to stock DS and to be honest sinking more money in to another possible DS is not ideal. WOuld the stock just be junk after a while?

Probably too much power for stock. I have an 18 A10 w/ the QA1 cf shaft making 872whp and have no complaints whatsoever. I would check installation. If it looks good, try reclocking it 180 degrees

I have the QA1 carbon shaft, mine is perfect. Agree to check installation.
