Brake Pads
Is the consensus that Porterfield R4S' are still the best street pads?
I have searched, but was wondering if there are any new pads out there that are worth looking at?
C63 P31 BTW too, though don't think that changes the pads?




If the OEM pads are making noise, they are probably glazed over, or haven't been used after getting wet. (Or are out of life. Do check that first! Just look at the pad on the caliper, you should always be able to see a few MM of pad at all times)
The fix if you have enough pad left should be good ole panic stops. Find an area where you can brake hard. I'd suggest going 40-50mph and then brake harder than you ever have before. Just slam on the brakes all the way to the floor. Let the ABS do its thing. Then drive for a half mile or so and do the same thing, but not so hard that the ABS kicks in. Now test and see if they are still making noise. Repeat a few times until the pads are scrubbed of the offending material.
When a car has P61 AND U70 (Grand Edition AKA 507) also A007 420 65 20
When a car has P98 (AMG Black Series) A 007 420 89 20

You drive a 450+ hp, 4,000 lb car that is designed to stop from autobahn speeds. There are no zero dust pad options. Best and no dust do not go together. I want 1000 hp and 100 mpg in a $20,000 car. Some things just aren’t going to happen

Being that the OEMs are easier to get here I might give them another shot for this replacement and see how they go.
They are definitely nearing the end of their life, so hopefully new pads and bedding them will fix my squealing issue!
If it's on, still you don't have to replace immediately.
so going off of everything I have been researching the last few days, it seems like the part number for the OEM brembos is 007 420 59 20, but I have also read that the oem pads are jarrid pads? Are the jarrid and Brembo the same?
also, when I look up the part number 007 420 59 20, it says they do not fit my 2009 c63. I do not have the performance package, because I do have the one piece rotors. Is this a mistake on their site? These have been the cheapest I’ve found for the front, and found some rear Brembo pads on rock auto for just under $39.

I have used rock auto for years, for easily 10 of my vehicles, and they have always been the cheapest. I am looking for OEM Brembo brakes, and if they truly are the same from rock auto, as everywhere else, why would I pay double-triple the amount? I will check out FCPEuro, but my question is if the links I posted, are the correct part numbers, not where to buy them. If FCPEuro is comparable in price, I would love to support a vendor.
Thank you.

To the original...OP, I recently installed Endless pads. Not great bite on winter mornings. But I'm leaving them there for light track duty so we'll see. OEM pads are awesome for the street across the range of temps. Happy shopping.

so yes, I did thread Jack, but only for the benefit of additional information for future members, and people searching through the internet.
My software was current to 2016 so I think that the part number is good.
However it was already once substituted.
Substitution is when they improve something with the part and change the part number. They leave in the software pointers, to send you to the new part number.
Maybe they substituted again in 2018.
So, to cut to the chase, I would call the parts guy at a dealer, read over the part number and have them validate it.
Also, to let you know, there's a note with these saying that the parts guy is to order a free document when this part number is ordered and give you this free document.
When I ordered my brake pads for the front, I asked for this other part number and the parts guy had to order it and give it to me, was a set of instructions.
