After searching through this forum looking for info on OEM part numbers for steel (i.e. non carbon-ceramic) front brake rotors for the 2014-2016 E63 (facelift model) I thought I might be able to add to the conversation. To the best of my knowledge:

The MB part# is 212-421-05-12. The OEM is Brembo. The Brembo part number is 09.A945.33. This fitment can be confirmed on both the MBUSA and Brembo web sites. The rotors are made in Italy (according to both the MB and Brembo boxes). From MB the price is usually astronomical (today on the MBUSA parts site they're listed for $1,720 each). The MB branded part can sometimes be found for less on ebay or elsewhere. On the Brembo Store USA site they're usually about half that price ($832 today) but they're just about always out of stock and sometimes not even listed. A recent email to Brembo USA confirmed the fitment and that they're often not available directly from Brembo in the USA but readily available from MB dealers. The Brembo branded part is not always easy to find in the USA retail market, but sometimes can be found for under $500 each.

The OEM part often discussed on this forum for 2014-2016 E63 and the one many retailers (including FCP Euro) say is the correct fitment is MB 219-421-02-12. This is Brembo part number 09.9764.23. Both the MBUSA parts site and the Brembo USA site both say this is not the correct part. Looking at the fitment table on the MB site, the part is correct for various AMG models including the 2007-2011 E63. The price is significantly lower than the correct part.

Comparing the two parts using personal experience at the dealer parts counter and the pictures/schematics on the Brembo USA site, it's apparent that the drilled hole patterns are significantly different and the hat colors are different (silver for the correct part and black for the incorrect). On the schematics, most key measurements seem identical. The correct part is listed as being a bit heavier.

So my only intent here is to attempt to provide info on what the correct OEM part is. Many people on this forum and elsewhere seem to have deployed the part for the earlier E63 successfully on the facelift model and of course there are many non-OEM options as well. To each his/her own. I ended up having my indy MB shop source and install the correct Brembo-branded part (they found a good price) and am very happy to have kept my car factory original. I know that's not something that's important to some others.

Hope this helps. Please correct any inaccuracies I may have provided.

Actually, for street use, I am happy with a quality OE or OEM rotor. (I did however, grabbed a pair of Genuine front rotors for the SL for a great price from FCP soon after I got the car. I have yet to install them (47k miles) since the originals are still in great shape.) I consider rotors and pads as wear parts to be replaced. Of course, my cars are not AMG versions.

To be clear, the "genuine" MB part being discussed here is manufactured by Brembo in Italy. MB doesn't produce their own brake rotors. Brembo is the OEM. The part is exactly the same whether it comes in an MB or Brembo box. The comparison I'm making is between two different parts, not MB vs. Brembo. Thanks.

Here are the pic and schematic of the correct part from the Brembo USA site.

Here for the incorrect but often recommended as factory correct part.

Genuine refers to Mercedes-branded items, regardless of manufacturer, as opposed to OE, OEM, and Aftermarket. Genuine just means you pay more and are assured you are using a factory part.

Brembo was NOT the OE rotor om my car.

Is your car a 2014-2016 E63?

Mojo20032004

I have been running the brembo 2 piece rotor for the last 20k. On my 2nd set actually. 2014 e63 S.. Mine did come with the factory brembo one piece rotor.

OldManAndHisCar

One of them. I forget what brand, 100% not Brembo. Or, your research not include "S"?

PeterUbers

same on all counts

This is what I am doing as well. Small decrease in weight with no tangible effects on braking performance. Win/win in my book. Plus the FCP replacement guarantee...

I am on my second set of replacement Brembo 2 piece front rotors (108k miles on the clock), they work great and look better than the OE ones
