Seems to be a lot of money floating out for the savings of 25 pounds, for a rotor with less weight, why not just remove the useless spare tire as most would never use it or know how to put it on anyways. Watch out for the whiplash with this weight savings.

Well, minimizing unsprung weight is pretty important from a performance standpoint, so a 25lbs reduction in unsprung weight is going to do more for reducing your lap times than a 25lbs reduction from the car itself. Ideally you'd get rid of both if you were after the absolute maximum in performance - but then again, you probably wouldn't start with a C63 to begin with.
As for the brakes themselves, the more material you take out the weaker the remaining structure becomes. All cross-drilled rotors will crack around the holes. If you were after the best braking performance as opposed to looks, slotted would be the only way to go. The directional vanes are IMHO a gimmick as there is almost no airflow inside the wheel well, so the one thing that matters most is the 'vented' surface area, and in that regard you'd want something like the dba 5000 series which unfortunately don't exist for our cars. For my money I'd be looking at something like the RBs for the C63, or slotted-only Giros. They don't look as sexy but work better and last longer.

Agreed 100%
5-6 LBS per corner will net you a faster pick up / launch.
Your car will feel quicker off the line due to less rotating mass.
This is an upgrade all C63 Owners should look into after there brakes are shot.

Hopefully not speaking out of line , but if the rotors ( any rotors) are a direct replacement it is the manufacturing companies responsibility to ensure all OEM components are functional if using their products. A non working E brake is not direct replacement nor advisable or acceptable.

The RacingBrake 2-piece rotors are absolutely amazing. definitely very happy. The only limitation is you cannot use a ceramic pad with them due to the super hard steel alloy they use.
I did a writeup on the 2-piece rotors you can view my searching my threads.
Hope that helps

Does the parking brake on our cars use the inside of the rear rotor hub itself? Never thought to even check... still running OEMs though.

don't mind me, but I am amazed at how we breathe life into these ultra-repetitive threads. brakes, tires, head bolts ... the three most posted topics here.

And still you read them, and then post, which puts it back on the front page.
Personally I find a lot of posts about drivetrain, suspension, electrical, fuel systems, exterior, interior, lighting, wheels/tires/brakes & racing. Not nearly enough windshield threads IMHO. In all seriousness tho - there is a lot of repetition. Ironically, with some issues, its a result of the sheer volume of posts on an issue making it hard to search for the one nugget you need.
Do you find there is less in the Porsche forums? I have only hung out bmw and infiniti sites and it was pretty similar there.

I have the same set up as Tal. Girodiscs and the Porterfield. Good grip, nice feel, no noise, no dust. And lighter.
As the English would say "A nice bit of kit".

I like the weight savings for the rear which is probably obtained by using an aluminum hub but using aluminum wouldn't be good for e-brake.

On the newer car forums, it's about the same as here. On the forums for the older, non-current cars like the old 944/951/928, there is less repetition, but I suspect it's because of the dwindling number of those vehicles that are on the road and the even smaller number that are changing hands.

Click here for our entire list of applications for Mercedes.
Racingbrake rear two piece rotor aluminum hats are designed without compromising the integrity of OE's emergency brake.
An iron sleeve is built into our rear rotor hat to allow the use of emergency brake. Do not be confused between "Emergency" and "Parking" brake.
"Emergency" brake is for you to use during emergency when your hydraulic brake system fails, while the "Parking" brake is for you just to park the car, if you forget to release it - immediately your hat is damaged if made of full aluminum.
Some known brands like Brembo or Stoptech advised customers to delete the rear brake if only aluminum hats is in the kit, or provide iron hats to retain the full functionality of E-brake which is what a responsible manufacturer and/or vender should do - clearly disclose the difference and advise their prospective customers accordingly about the impairment of brake system.

Yet another reason why IMHO the RBs are a better choice. I like the write-up on your site about the convergent vanes (in line with my earlier comment about the dba rotors) and that the rotors themselves are balanced before they're shipped out. Am always glad to see sound engineering principles and science behind any product.
