A lot of cars here in Korea are covered with 3M protection film. And it is very clean installation using the largest sheet available. Certainly better than most american installations I have seen when I lived in the states. Most Enzos Zondas DTMs Exotics and AMGs & Ms are covered with protecition film to keep the resale value by protecting original paint from stone chips. Costs about 3G to do that. It is normal here considering the fact that the price of any import cars cost almost twice as much as the price of the US. because of one accident or a paint job on the hood or just a simple swap of door skin without any internal damages of the door parts, owners can lose upto 20G on AMGs here. Now think about it. What would you do?

Maybe I'm missing the point.............but why would you go to all that trouble and expense for 10rwhp?
There are tons of mods which would give better bang for the buck.

I dont see how a lighter propshaft is going to make any difference to max power ... what it will do is make instantaneous power delivery more direct as there is less inertia, and the energy originally used to move the old prop mass is now moving the wheels... I am not so sure this remains the case when you get to max power as the speed of the shaft turning reaches a peak and there the differences are no longer inertia but friction. These differences between a light one or a heavy one are minimal in my view. So you will have better instanteous response -- but I doubt vmax would be any better.
In our cars with this massive torque delivery I would think a carbon fibre prop shaft could quite easily be shreaded especially where its mated to the metal coupling ...
Can some engineer (or any one else for that matter) explain if and why I am wrong please?

Because it is always good to have other options available when people are only talking about pulley and ecu and header and cams and etc. WHy not driveshaft? I say. Because those obvious mods are maybe too boring in my taste?

On a percentage basis, there isn't much improvement considering the 55K's already put out ~500HP/500lbft, are relatively heavy cars, and have relatively heavy drivetrains. Might not notice much of a difference in RPM gain given that the SC drags that down.
If you could find someone that can do it cheaply, then yeah, it's a route.
I actually go with lighter driveshafts to solve harmonics problems with live-axle American V8 musclecars. The harmonics isn't much of an issue in the 55Ks with our 2.65 ring and pinion and our independent rear suspensions.
Oh, that's another thing - 2.65 ring and pinion means the driveshaft isn't spinning as much at any given mph as say, a car with a 4.10. So, benefit would be even less in our cars.
