Can anyone confirm that the Brembo 2-piece floating front rotors will direct-fit replace the stock (non-carbon ceramic) front rotors for 2020/2021 C63S coupe? If not, are there any additional parts that need to be ordered to make the fitment work? See attached pic for the part I'm referring to.

Not sure of that part # but I've been running 2304211212 on my coupe for a little over a year now and they have been great. Just wish I could find some rears that would fit.

Speeddoc

Thank you. I will check that part number out.

Those rotors are 390 mm x 36 mm. Are our stock front rotors also 390 mm x 36 mm? Are they a direct 'Plug-and-Play'?

The 360x36 mm rotors are for the non-S C63. I know because that's what I used. If you have the C63S, you will need the 390x36 mm rotors.

I started a thread on this topic a little while back and it has links to the ones you want. Just run a search and it should come up.

You need this one.

The one you posted are 360 mm diameter. You need the 390 mm.

Speeddoc

Thank you. Yes I have the C63S

No other parts needed, installed myself. Yes, they are 390mm stock. The part # I gave you is correct.

Speeddoc

Thanks again. I appreciate that.

Do you have a recommendation on best braided-steel brake hoses?

No prob!

Now if someone could help us source some 2 piece brembo rears that would be very helpful since I have yet to come across anyone that has done it. I've seen the platz1 2 piece rears but they are missing the veins. Would also rather get Brembo. There has to be a spec that works!
I attempted the rears at the same time as doing the fronts but failed - bought 2304231412 (360MM x 26mm) originally for 05-11 SL65. The hat was 3-5mm too deep and didnt line up with caliper/pad but all other specs were met . Didnt want to attempt a spacer behind as that's not safe. Another thing to keep in mind is drum or actuated parking brake. So if anyone is trying to find a solution for the rear, avoid the rotors I mentioned above and save your money!

Any others that could offer further insight would be much appreciated..

I run stock lines but another member on here recommended goodridge.co.uk (not available in their US store) and mentioned he had good results with them. The only other kit I've seen for the platform is gruppe m which they want $400 for 4 x short lines, no thanks!

Speeddoc

Thank you.

i made custom hats for those rotors. work like a charm on my c43

Did you make them or buy another set of different size rotors with the correct size hat and swap them out. The "4444" smeared on the side looks like a brembo part. Please hook me up with the info! Nicely done
