Is that DSS driveshaft made of carbon fibre? Thanks for pushing the envelope!

yes It is !!! I guess one limiting factor is torque management by our ecu... I am having trouble witn my since when the ECU senses high torque it closes the throttle body and the appears to into limp mode and all of the sudden at 5,000 rpm it unload the power and it hammers the driveshaft....that occurs when you step on the pedal a full blast and it down shift into lets say 3 rd gear , but if you paddel down into 3rd and step on it, then it behaves normally....

my car is a 2013 model... I read somewhere that cp and newer model have an upgraded differential that manages torque better.... Does anybody knows?

Someone needs to find the weak spot of these rods and pistons lol, crazy if 870/900 is a "safe" number on stock motor lol.

I think the upgrade is purely software related.

That's what Sport Auto said, In CP models BMW have improved the differential and now it puts down the power better.
