Time for new front rotors
I was just told my 507 failed the Virginia inspection due to wear levels on my front rotors. I'm not exactly wanting to pay the $3200 for new rotors and pads at the dealer. I know the OEM set up is actually very good. I was thinking about going with the Racing Brake set up at the following link http://www.racingbrake.com/Mercedes-C63-AMG-Brake-Package-p/mb-irk-18.htm
Any recommendations or input?

Time for new front rotors
Wow, already? How many miles and have you tracked your car a lot? Seems a bit early for the rotors to be below state inspection limits. Dumb question, but was the inspection performed by the dealer or an outside inspection station?

I'm looking at the exact same thing. Waiting for my mechanic to check whether my rotors will pass inspection/on their way out.
I thought of going Non PP OEM Fronts too, but...my car came with the P30 Package, it feels wrong to "downgrade", haha.

First off I would just take your car to a gas station for inspection and they will likely pass it. The Shell station next to my house is <10 mins in and out if there's no line.
If money is an issue I would switch to the regular C63 rotors and save a couple grand. The vast majority (80%?) of C63s came with them and they work just fine. $150 for regular rotors vs $750 for the PP. Take that extra money and spend it on your kid. You won't mind the ~10lbs of extra weight on the rotors. You can always get better rotors later.

OP, as you are mentioning you are familiar with RacinBrake as an option. Here is a thread on their big brake upgrade kit, in case not seen.
https://mbworld.org/forums/c63-amg-w...their-car.html
The RB rotors are indeed better than OEM (harder and you can replace the rings only/keep the hat), which reduces cost of ownership further in the long run.
Whether you want the same dimension as stock or the larger Black Series size, depends on what you want to use it for. The larger ones have spectacular stopping power, but cost more and are not compatible with 18 inch rims. I think also with the standard size RB rotors you cannot go wrong.
I personally do not get it, how folks can recommend to go with single piece rotors on a 6.2l displacement 3900 lb car. If you need to save a couple hundred bucks and do not care about drive performance, you probably have the wrong car. My humble opinion........

So just to clarify....
1) all AMG development package cars (P30, P31, P88) have 2 piece rotors
2) can we not buy just the rotor vs rotor and Hat. ....
3) is the price of $750 for rotor and hats or just rotor?

2) Mercedes does not sell just the rotor. Aftermarket companies do offer just the rotor for their own applications, but you have to buy their new whole rotor first.
3) The whole thing since you can't buy just the rotor part from Mercedes.
Because EVERY C63 without the AMG development package (ie a good 80% of them) came with the solid 1 piece rotors? If it was that important to the car's design every C63 would come with them from the factory. The rears are also single piece on every C63. You know what's more ridiculous? Mercedes selling a 507hp car that didn't come with a factory LSD standard.

Yes, the 750$ would buy you one OEM 1.5 piece rotor via mailorder, or 2 replacement rotor rings from an after market 2 piece vendor like RacingBrake.
Agree on the LSD - but that was just a way to keep the list price down I guess. LSD was the first option I asked about when test driving.

Update: I did pass the inspection at a gas station inspection station. I don't plan on driving the car much between now and next spring, nor will I will be doing any track days so the current brakes will safely last me until that time.
I will definitely be looking into the racing brake set up at that time as I like how I can upgrade all four corners for less (standard) or only $1,000 more for the larger/BS size. I'm thinking Fathers' Day Present.

Does anybody have any insight on the Racing Brake option vs the Girodiscs? Both very well known companies, with it essentially being the same price either way for their "Stage 2" Packages anyways.

I currently have the tune off as I need to get the US COMAND system and maps installed when the disc comes in and I revert it to stock whenever taking it to a dealer. I cannot wait to get the tune put back on though.

I don't see anything wrong with going for SS Lines. I'm pretty sure Tal can deduct them from the package price if you don't want them also.

Regarding Girodisc vs RacingBrake: Girodisc only offers replacements for the front rotors, while RacingBrake also offers solutions for the rear, e.g. a larger rear rotor with Black Series diameter, but fitting to the stock parking brake drum on the C63. Also 2 different front rotor sizes.
If all you want is new brake pads, there are many more options including Brembo, Ferodo, Hawk, Pagid, Performance Friction and others.

For C63 owners, other than just swap the rotor:
If you upgrade your front to 390mm (from 360) rotor, and rear to 360mm (from 330) your brake will be same as Black Series, yet you still retain your emergency brakes, because our rear rotor hats are custom made to fit C63's smaller drum.
If you just replace your front (keep as OE's 360mm) and upgrade your rear to 360 (from 330), you will have the same brake as E63 (pre 2010)
We made a similar offer for pre 2010 E63 owners to upgrade their front to 390mm (from 360), so to make E63 have the same brake as S63/S65
Upgrade as you replace is a sensible investment that's only available from RacingBrake.

Another option worth checking is Coleman http://www.colemanracing.com/Default.aspx. They built a set of rotors to my specifications for my Mazda RX-7 a few years ago I've been happy with. They have a form you can fill out with all the relevant dimensions and they will build them. I don't recall the cost but they weren't expensive. This would allow re-use of the hats. You'll need new bolts which they can supply if you know the size and thread pitch. Be sure to use some Loctite and safety wires though.

Yes, I did see that RB has offered a solution for the rear too to size it up to a 360MM. I'd love to run that, but then we're going from $2500 to $4200, and having to refinish the front calipers in addition to that too.
And, the problem with that is, is that Hong Kong has yearly inspections, and I'll have to remove and reinstall the OEM Rotors on the Front, as anything with an "Adapter/Bridge" on the Caliper won't pass.
That's why I was looking at OEM Sized 2-Piece rotors, which I know RB also has. Was just exploring more options!
Good point, RB offers a total brake solution beyond just parts replacement.

I mean, then that way I could run the 390s up front, and the 360s in the rear, but without having to pay extra for the BS Calipers and refinish too?
However, I woudln't be surprised that you noticed the reduction in rotational mass. I myself have always done 2-Piece Rotors/BBKs on all the cars I've driven, and it does feel nimbler. I wouldn't say it's a "huge" difference, like lighter wheels, but it is slightly noticable.
Rotational mass, saving 28 Lbs of Unsprung Mass, is quite a big difference! It's like going lightweight wheels! But, AFAIK, because it's closer "inside" the car, and not as far out as the wheels, it's not "as" noticable.
