C300 4MATIC upgrade braking options

I have a '11 C300 Sport 4MATIC. I know my options for upgrading the front rotors and calipers are nil because of it being AWD. I still like to upgrade the rotors and pads though and one of my questions is what is anyone's recommendations for the front. As for the rear rotors and calipers, they leave a lot to be desired, so should I go with the AMG upgrades or would there be too noticeable of a difference with the stock fronts calipers? If not AMG upgrade for the rear then what would you suggest?

Thanks

There are several aftermarket options that will work for front and rear. The AMG upgrade issue by Brembo and with stainless brake lines it would be a huge upgrade from stock. There is also a forum sponsor that is or was selling a Alcon front and rear big brake kit with rotors that I would personally choose over the AMG kit. I ran the Alcon/Stasis list on my Audi A4 and loved it over any Brembo kit I've ever used.

See if Sponsor Racing Brake has a 2 piece rotor solution. I don't know about caliper options as the OP does. One does not use ceramic pads with RB rotors since they are so hard versus stock MB, AMG or aftermarket solutions. Semi-metallic pads of your choice would be the sensible option. If there is enough demand and Warren does not have the solution already he can make them up since he has access to proper engineering specs. I have placed an order for my CL55 front and rear.

I agree with my friend above that Brembo is not what it is cracked up to be and is expensive.

Search the ML63 forum for one of the first implementations. Oh, RB is running a group buy for MBWorld members.

Front BBK (328x28) is available and Ready to ship

RB brake kits for Mercedes are customs designed to properly (in size and look) fit behind your C300 wheels.
ey feature of RB calipers are:
  • Pistons are of Stainless Steel (vs. OE and other aftermarket kits with Aluminum)
  • Internal Dust Seal (vs. external dust boot, so no crack boots due to heat)
  • Tight offset (1.1"/27.7mm) for less flex under heavy braking.
  • Powder coating: Red, Black, or Blue with RB logo for an attractive look and lasting performance.

Rotor weight comparison:

OE 1pc = 18.6 lbs (295x28)
RB two piece = 16.8 lbs (Still save 1.8 lbs/rotor even it's 33mm=1.3" larger @328x28)



Please feel free to let us know if you have any further questions.

Not yet but we can make matching rear two piece rotor BBKs available.

OE rear is a 300x10mm, non-ventilated (solid) rotor, and our brake kit will use ventilated rotors and larger size to match up the front BBK.

What you have in the front.

Thanks! Will these fit the 4MATIC upfront? I will be upgrading my rears for sure. From what I have been told though I am stuck with the stock calipers upfront because its 4MATIC. Though i know there are options for replacing the rotors themselves. It already stops fairly quickly and had someone drive it and first comment was how much better the brakes were compaired to there Accord.

What do you find lacking with the OEM brakes? Do you do HPDE's?

With stock rotors, you can get high fricton pads that grab like heck. Porterfield R4S Street/Track pads are high cold grip and low dust.

On my 93 Rx7 tracked car, I ran oem rotors, Porterfield R4 Race pads up front, and the R4S pads in the rear. Tough track braking from 130 to 45 at turn 1, Summit Point. At the end of the season, I put R4S pads on the front too.

None of that. I usually always upgrade ECU tune, brakes and suspensions on my new cars. It actually does already brake very well now. Just thinking of upgrading the front pads and rotors and for the rears the rotors, calipers and pads.

After different phase of upgrades, at the end you might find out "ONE" time complete BBK upgrade like we are offering here is probably still your best choice (in value and time saving)

With this one time BBK upgrade you are instantly switching from "stock" to high performance brake package, not only it allows you have a better control over your C350, but save your maintenance costs - Our pads use the standard FMSI# D647; Most used in sports stock cars like Nissan 240S, 300ZX, Subaru WRX).

Plus the enhanced beauty behind the wheels, and with our low dust street pads your wheels will not be covered with filthy black dust all the time and save you time in keeping them from a "decent" look.

Contact us for the introductory offer, or if you guys think you have enough interest for a group buy.

Thanks

It seems you have made the 1.8 lbs saved per corner a significant advantage. Sounds trivial to me .

It sounds like it but just think of this; If C300 being the stock size of 295x28 weighs 18.6 lbs, with the same style as MB rotors at 328x28 it's estimated weight would be ~ 25 lbs.

So my 1.6 lbs per rotor is comparing to stock size rotor, but if comparing to the same size as BBK (328x28), the weight saving will be approx 8 lbs per rotor.

Hope this makes more sense to you.

You are now comparing your rotors (excellent as they are) to a hypothetical rotor that does not exist. And you confused the weight advantage more, by introducing the hypothetical 8 lbs per rotor.

I don't question your product's increased performance over oem. However, as I said before, the real 1.8 lb saved per corner is trivial, compared with the curb weight of the car, and the hefty total unsprung weight per corner.

Ok Ok

I have the Sport Package, so my front rotors are cross drilled and it does brake real good now as stock. Been told by someone else who drove it once. What I would like to do is improve upon that. Now I know the AMG brake kit will fit on the rear no problems. Ive heard though that the bracket for the front on the AMG kit can me modified to work with the 4MATIC. I'm not sure if I want to do this though. Now this BBK setup being offered by RacingBrake, it does nook nice. The questions has not been answered, will it fit with no modifications or fabrications on a '11 C300 4MATIC?

Or should I just upgrade the rotors to R1 Concepts Premium Cross-Drilled 2 Piece's? and some good low dust pads.

The problem with sticking with the stock calipers is that i would like to paint the red and the rear ones. If you look at the rears in the picture i posted originally ... there isn't really much meat on the caliper to paint ... hence why i like to upgrade them ... and if i upgrade the rears ... how out of whack will the look with the stock fronts ???

I thought the w204 does most of the braking from the rear brakes?

Also, if you're not doing track or high speed runs, you really only need to upgrade your pads, lines and fluid (no rotors since you already have sport rotors) BBK's are nice and all but really wasted on a street car. I upgraded to DBA rotors, ceramic pads, SS lines and DOT 4 fluid, I stop well enough faster than the stock equipment and this is even on highway runs.

Do you have a 4M? I have the sport cross-drilled rotors in the front, if you look at the rears though, it leaves much to be desired. I want to upgrade the rotors and pads to cut down on the brake dust. I not want to buy 1500$ a piece HRE's wheels and they just get eaten up by brake dust.

No I don't, whats the difference between 4-matic rear brakes and regular RWD models? My point was that for daily driving, better rotors, pads, lines and fluid are more than enough.

wrong Kevin

the rears on RWD and 4M are the same and the 4M can take the AMG's in the rear with no problems. It is the FRONTS on the 4M that no one seems to make an upgrade kit for, though someone said you can modified the bracket so that is works, front AMG kits that is ...

You are spot on, except about which end does the most braking. You start with some front weight bias, and then consider the weight transfer during hard street braking, and that pair gets you d to about 80% stopping done by the front wheels.

For most german cars that must have TUV approved, "dirty" pad material, you can see how the front wheels are much darker than the rears.

I'm only speaking based on something I read once (which coincidentally I can't find now) that at low speeds the w204 brakes more from the rear and that at higher speeds it brakes from the front.

Oddly enough, after my car washes the rotors seem to back this up so I'm not sure. After a carwash most ppl will end up rust looking rotors, the drive home from the carwash to my home doesn't slow me high speeds but I always end up with clean rear rotors while the front rotors are for the most part still covered.

I heard this too ... reminds me of my youth ... dirt bikes use the rear brake almost exclusively ... while street bikes use the front brakes ..

That's good confirmation that only the rears are used at low speeds, like driving on icy roads ...

I'm sure the front pads are larger than the rears, and the front disk is wider than the rear, suggesting that for "averaged" braking conditions, the fronts do most of the work ... me thinks ....

W204 C300 CDI 4-matic -13, W124 500E -91
Hello,

Old topic but intresting has anyone tested or done brake upgrade for 4-matic? I did not find answer from this topic that are the AMG brakes compatible with 4-matic models..
Are the W204 C63 AMG calipers bolt on to front axle of 4-matic?

If not, are the mounting brackets different or AMG brake disc won't fit to the front axle hub, etc.?


Regards,
jnes
