ok, besides he fact that the rotors are multi piece, and the calipers are red, does anyone have any info on what the "AMG Compound Braking system" consists of what?

does anyone know?

Ceramic compound brakes (like the Porsche cars have), no?

No, simply a different compound pad, calipers and rotors are the same.

i thought the rotors were three piece? are the standard rotors 3 piece? the pads are not ceramic? damn, that means dust........ i'm so used to having no dust on my c32 with ceramic pads.

Ceramic brake packages average close to $10,000 as a stand alone option on many high end cars. They are not included with the SLS but I did see a magazine write up on the E63 that showed them as an option.(The calipers were a bronze color). However the option list on the AMG website does not mention them. Don't know what the "compound" is but it is not a carbon/ceramic setup.

The SLS has what they call "high performance composite brakes" and as an option "ceramic composite" brakes.

I still don't know what they mean by "composite brakes"

Good question.

Refers to the rotors. A "composition" of two materials, in this case a steel disc and an aluminum hat bolted together. It's done for two reasons: To reduce unsprung weight and to dissipate heat.

For instance on Porsche's, you can order composite brakes, but the difference is that the disc instead of steel is made out of Carbon Ceramics bolted to the aluminum hat. Not only is there a big price difference, but they also need higher operating temperatures to work properly.

Yes, sir. Driving on those carbon brakes early in the morning while they're still cold can be a scary ordeal.

And when they get very hot they can catch on fire. See top gear SLR test.

They sound like the exact same 360mm composite 6 pots that are on the W211 E63.

So are the P31 brakes just E63 brakes(?)

The ceramic composite option is something totally different than this, of course.

Same brakes as P30 now, just red calipers.

They don't look the same as the P30 on the website.

The caliper looks the same in red but the rotor looks quite different. On my CLK Black the compound rotors have aluminum hats and you can see the screws that attach the hat to the rotor.

This picture doesn't look like that at all.

These are the p30 brakes:

I have Brembos on my M5 and the rotors look essentially the same as the P30 rotors, both components being fastened with small bolts. The new P31 rotors definitely look lighter but also quite a bit cheaper to manufacture.

can you elaborate on how it is cheaper to manufacture?

I'm not seeing any bolts on the P31 photo. If so, the components must be pressed together somehow. I am contemplating changing the the rotors on the Brembos on another car and it is a bit of a PITA with disassembly and reassembly of the bolts and clips...much more time consuming than the P31 appears to be.

There really shouldn't be too much confusion after this post

wow, it's all clear to me now........

Can't get any better than this...........you answer a question and this is what you get?

We should have two here at the dealership within the next week or so. I will post up some pics so you can see what you have waiting for you in Germany.

Thanks. I'll ask the guys in Sindelfigen what the difference is between the upgraded brakes and the stock. sounds like the same materials, just 2 pieces, with the bolts and the red calipers. From what i can tell it's the same calipers, but in red.

Does anyone know whether the calipers are the same between stock/base and P30?

Specifically, if you have a C63 without the PP (P30/31), can you retrofit the compound (2 pc.) rotors, without changing anything else?

Old p30 or new? Or does the picture just now show the slots in that rotor?

Yes

^ I will try and get confirmation for that too tomorrow along with part numbers for base, P30 and P31 calipers, rotors, and pads.
