Besides the aesthetic value, here's the performance argument....

You're quantifying the use of stopping power as a component of velocity, when I would argue that stopping power is also a component of speed. True we do not have the power of say a C63, but that just means we do not accelerate to stable speed as fast. Once we reach relative stable speed, the power argument goes out the window. At similar mass, traveling at similar speeds, if you need to stop on a dime (say due to an accident in front of you), an underpowered C300/C350 gets just as much benefit out of the stopping power of BBKs as does a C63.

And having had both brakes, it's a huge noticeable difference in stopping power and has probably saved me at least once from stupid drivers.

I am sure there will be ways to justify the purchase However, I still think that for the price, upgraded pads, steel braided brake lines, and fluids- you would see similar or at least comparable performance differences for a far cheaper price. I am assuming that these parts are available aftermarket for the C class.

I think it looks nice, no doubt, but then again... too much cost for benefit - at least, for me...

It does look pretty though.

Well then, to quote yourself when you did your projector retrofit, gotta pay to play right

And as I stated before, the performance difference is pretty huge between the two actually and you'd have to really have them to appreciate the stopping power.

Here is what I do not understand; We are the largest Mercedes Benz Tuning dealership in North America. We visit SEMA every year to look at new items. We saw Rotora display. They kissed up to us etc. I e mail them on their products and nothing in stock. I then asked about dealer pricing and there was no discount? It was only 5%. Keep in mind, companies go to SEMA to seek out buyers in our industry , it is not open to general public. ( you could get in if you really wanted) Why would you go to SEMA and then try to sell your item retail to dealers? It seems that Rotora wants all the dealers to work for them, making them all the profit.
Also, again, their staff has no experience as much as Brembo does...
and if their are any issues, i truly believe that Brembo will stand behind their products.

AZN C300, your post about similar mass sounds and at hwy speed sounds interesting but unfortunately it is far from the truth. BBK's are meant for repeated high speed stops which is typically done on a road course or race track. BBK's in the situation you speak of provide no real benefit unless you were going above 100mph when brake fade may pose an issue. The original equipment brakes are more than adequate to stop the C300 with standard wheel and tire setup. With aftermarket wheels and tires substansially wider than factory setup the BBK may also benefit. Other than that it's a wash.

I'm very interested with this price quote.. where to get them from for W203? or perhaps AMG SLK55 4 pot rear calipers are much cheaper?

Right, you'll get less brake fade and that shouldn't be an issue as you stated unless at high speeds. You'll get the most benefits going high speed (100ish) to zero as stock brakes can overheat which is what I was going for in that example. They do provide better clamping under hard braking resulting in less pad tapering though. Repeated heavy braking can be achieved by a simple downhill spirited mountain twisty run.

The performance benefits will vary situationally, but like I said, obvious main reason for getting BBK is aesthetics.

hey guys this is my first post. really thinking on getting a 06-07 C230 or a 08+C300. and just doing lots of research. and brakes are something that i upgrade first on a car. I have a 02 camaro Z28, and just upgraded to CTS-V 4 piston Brembo calipers and 14" rotors on my camaro and what a difference, looking to complement the rear right now.

n e ways I was curious have you guys looked into stoptech at all? they make quality BBK, their Calipers are comparable to brembo's far superior than Rotara. I see they offer a 4 piston BBK for the C230's but nothing for 08+ or atleast it hasnt been updated on their site.

The C63 have different spindles than the non AMG cars, but how that affects the fitment of 63 caliper and rotors I do not know.

Azn_C300

To my knowledge, Raver's the only one who has put on OEM AMG BBKs on his non-AMG 204.

Peabody

No. I'm reconsidering a brake upgrade after running a few laps on the Nurburgring and having to pull off the track to let my brakes cool down as I was feeling them starting to rapidly fade. I'm sure for driving in traffic, the stock brakes are fine but if you want to do any kind of performance driving, they are going to come up short.

tls1212

for the c63 brakes to non AMG 204 ,you cant use the original caliper bracket from c63 you have to use custom one bracket (you can source from taiwan) there is a seller selling this bracket for non AMG 204 simply direct fitted without any modification.I have done mine few month ago

Robbio204

What does that mean? lol That makes little sense.

Sportstick

Actually, makes perfect sense and, as usual from Michael, well said!

70 mph is 70 mph....doesn't matter how long it took to achieve it...stopping from that speed is the same for a fast or slow accelerating car.

Robbio204

Okay, I understand that part, I am saying the part I quoted from him. Velocity is speed with direction. Forget it, I'd rather not go on with nitpicking.

Sportstick

It's a slow night, so......Nit!

It's rate of change!

Krytech

Can anyone with knowledge comment as to whether or not the front rotors on the C350 could easily be installed in the rear? I know it's a long shot but it would allow us to buy a BBK for the front and put the front setup in the rear.

zzz...zzz...zzz (that's me dreaming - feel free to wake me up)

Robbio204

Please look at the link that you posted. Lol

"For example, "5 meters per second" is a scalar and not a vector, whereas "5 meters per second east" is a vector."

Robbio204

Regardless of whatever that sentence,about quantifying velocity vs speed, means, or was meant to say, we can both agree on the second part lol (the 70 mph is 70 mph) lol

Azn_C300

Velocity is the delta of two points (distance) over delta of two times(displacement). Has nothing to do with what direction. This is totally different from speed which is instantaneous velocity. This is your MPH at any given instant. When measuring Speed, how many horses you have under the hood doesn't matter because the two subject vehicles have both achieved relative speed (regardless of how fast it took them to get to that speed ie velocity).

Azn_C300

Right, ok, but what I was saying was in regards to the example direction doesn't matter as the two vehicles are traveling in constant direction. I do yield (after rereading this thread) that I did misspeak as the displacement then in that example is the same as distance as there are only two measured points for Δx. The overriding point I was trying to make then was really when the two vehicles reach relative velocity (at cruising speeds) vs max velocity in regards to the benefit from stopping power.

great michael

perdikoula888

This is totally incorrect. You can fit c63 hubs to normal non amg 204 and fit the c63 brake calipers wth no problem. No aftermarket parts required, neither I would ever fit custom taiwanese brackets as they might be a serious safety risk.

Mr Enigma

+1 that it didn't make too much sense without your additional post (#45), but I did understand the message in the original. Nicely put.
