Yes there is room for improvement on the drivetrain including axels, driveshaft and diff but they seem to be holding up if you don't launch the car from every stop sign.

Ok let me explain and please correct me if I am wrong.
The difference between whp and flywheel hp is the drivetrain loss which is 12-15% for our cars so basically if you claim your dyno measured 800 whp (800 hp at rear wheel) it means your tuned engine is generating 12-15% more power or 900+ HP right? having said that, you are transferring over 900 hp to transmission input shaft and something about 800-850 hp to drive shaft and almost the same power to axle... not saying it's not possible but for sure these components are not rated to these numbers. on the other hand your DCT is rated to 700 nm (516 lb-ft) as a safe number; however I believe up to 600 lb-ft is safe since German's are conservative... now please let me know by 800 whp you meant your dyno measured 800 hp at wheel or that's the number after drivetrain loss correction?
meanwhile you said if we do not launch.... I believe this car is produced to be launched with no restriction... what you are saying is like to say go to restaurant but don't eat anything then you are fine
