For a Canadian C300 4matic w/ AMG sport package, what brake pads and rotors should I be getting? Lurking around the usual place, ECS, rockauto, there's various makes... just wondering what to get and where to get it from.

Not sure if my C300 is the 4Matci Sport, Luxury or Sport

Thx to all

Speaking from experience; ceramic compounds work great in warm temps, not so much in cold environs. Check out ferro carbon compounds which are a good compromise and a bit more gentle on rotors than semi-metallic. As for brands; I've had best results with Brembo, but Akebono, Textar, Ferodo and Bosch are all quality products and over the years (including racing trim) I've used them all (including Porterfield) and found Brembo to be the overall best choice. Who'd of thought that the number one in racing brakes turns out to be the best?!! Cheers

R1 Concepts has a good product. My buddy has a set of them on his M5.

Good price too!

Aekebono Euro's will help cut down on your dust. Solid brake feel, no fade and less dust is a winner for me

Is anyone running the Stoptech 309 pads? I've always had good luck with these.

On top of the break question. Have you or has anyone though of getting same size drilled rotors for the back as the front?

I have been curious if there is a way to just take the same size caliper and rotor as the front and throw it on the back, without dishing out like $2k.

I doubt it. Because the calipers are different sizes, the caliper supports are also different sizes. You can check to see if the caliper support from the front wheel has the same mounting holes as the back, but I doubt it... I seem to remember someone trying to do an AMG brake swap and this issue coming up.
Mind you that was in 2013 or something.

I know this sounds like a good idea, but there are a few reasons not to do this. Brake modulation is very important, if you have the same braking power in the rear as the front you will just lock up those rear brakes. The extra weight at the front of the car and the weight distribution under hard braking puts a much higher load on the front brakes.

+1 I figured I wouldn't get technical because I know the caliper supports don't fit so I figured it would end pretty quick.. Hahaha.

Brakes are sensitive.

The setup should be such that the rear brake is big enough that you reach maximum grip (without OVERSHOOTING that grip i.e. locking the tires) the same time you hit max grip on the front brakes, because you put a lot of extra load on the front of the car during braking, the front tires have a lot more grip hence you can put a lot more breaking force on them without locking the tires, this is why you need bigger brakes on the front.

Mind you, the stiffer your suspension, the more equally your brake sizing will be when optimized due to less weight being thrown around from dive and suspension geometry changes. (this is NOT to be confused with BIGGER brakes, in reality, the stiffer your suspension (provided you add no extra contact patch via tire size or other and you don't add any extra downforce through aero or weight) then the SMALLER your brake will be because you will have LESS grip.)

Or at least that is how I've been taught/researched.


Brakes are the second most important part of your car besides tires. Mind what you do to them.
