Mates,

I pulled the trigger on the Black Series Brake kit upgrade for my c63.

NOTE: These RB rotors are way lighter than stock!

I purchased the kit from Racingbrake.com. The company is local to me so I picked up the parts and saved some money on shipping.

Front rotor kit: https://racingbrake.com/one-piece-ro...quattro/2457-k

Rear rotor kit:https://racingbrake.com/standard-iron-brake/mercedes/2458

I went with the XT910 front and rear pads.


You can keep your front calipers but will need to use spacers (which racingbrake provides).

Total cost for the RacingBrake parts was less than $3,500

You cannot retain your rear calipers. You will need to use the following part numbers for the rear brakes if you wish to retain the red calipers:

Left caliper: 212-423-68-98
Right caliper: 212-423-69-98

The big brake kit



Note: For those interested in upgrading your brakes to front:390mm and rear 360mm you will require 19” wheels so that the rotors and caliper will have enough clearance.

These brakes lasted 96,000 miles but it was time for a change.

During the install:




Front brakes:







Rear Brakes :




I decided to go with junkyard E63 W212 rear calipers that I was able to purchase for $500 for the pair. The rear calipers are pretty worn down asthetic wise but it does not bother me as I will be professionally painting the calipers in the near future.


Stock rears:



After installing the bigger rotors:




Overall the bigger brakes dramatically improve the look of the c63.

I did not get to drive the car much after installing the brakes so I am not able to honestly provide an opinion on the brakes yet but I will be posting my review of this kit after I break the brakes in.

Stay tuned.

You knew about this thread right? A bunch more info in it as well.

Went with the Racingbrake 2 piece rotor upgrade kit 360mm 2 years ago. Top kit! Well worth it. nearly 40lb unsprung weight savings!

Only issue I had were the XT910 pads were a tad too hard and not quite suited for day to day driving. More for track. Mine was glazed under 800miles usage.
Otherwise, the rotor still looked barely used even after 15K miles.

Unfortunately due to COVID 19 I was not able to test these brakes at the track; however, I have decided to test them out street/canyon driving using XT910 pads. I am running stainless steel lines in the front with OEM DOT 4 fluid.

So I took the car to the canyons after bedding the brakes in. Drove approximately 60 miles. 30 miles up the canyon and 30 miles down the canyon.

The difference between the stock rotors and the RacingBrake rotors are night and day.

I know most that purchased these for track but I honestly got a lot out of them just on street usage alone.

The brake setup now has WAY more bite than before. They stop on a dime! Under hard braking (100 to 40 MHP) the car does not lose ANY control whatsoever. the brake bias is also set perfect. I can easily RACE the canyon windy roads faster than I was able to before.

I can also confirm these RB brakes dissipate heat better than the stock brakes. I am happy with my purchase. I do feel the brake kit is priced competitively for what is offered. You sure do get a lot more for what you pay for with RacingBrake.

A buddy who runs RacingBrake on his C63 told me about the bigger brake kit upgrade for our regular C63. I just wanted to offer my honest opinion. I hope that is okay.

Nice review. Do everyone a favor though and stop RACING in the canyons, you inevitably *** things up for everyone else.

SikC63

Not to worry Mate. I tested this out in the middle of nowhere.

What is not surprising is the cost of gas out there.

Jasonoff

Not sure what you mean. I was just pointing you to a thread with a bunch of info in it that my interest you.

SikC63

Thanks mate.

Posted new thread so as not to hijack

RacingBrake

We all appreciate your candid review and opinion.

The original kit created by RB is still the best. Idea can be copied by others but they will never be the same in daily performance gain & driving comfort, the outstanding design of center mount design, the rear true light weight two piece rotors retaining OE drum emergency brake, and overall lasting durability.

i don't see why it's a hijacking, competition is healthy and good. You should help to bring all discussions relating to the same upgrade to this thread, comparing feature to feature and put everything under the sun so members can see themselves. Or post a link where your discussion is.

Jasonoff

Any reason why you won't sell the front bracket separate?

for those interested i believe the original poster pulled his 390mm kit and is selling as a complete kit.
