this is size for c63 Black Edtion

CarHopper

Why not just get the C63 brakes that are on there? 360mm x 36mm instead of the 390mm x 36mm like those.

-- You have started a lot of expensive threads. Hope you plan on tying this all together at some point.

i already order stage 3 supercharger and full exhaust system... and looking for good stoping power... i think 390 mm will stop way better no ? why should stay on same size

MagasC63

Not to get off topic, you actually bought the stage 3? I thought you stated that it was too much of a risk etc? From what it sounds like, you bought it. Welcome to the club and congrats bro. Make sure you upgrade the trani, or atleast get the TCU/valve upgrade.

alpha26

yes i was thinking is danger for a tranny but after speaking with Sean@Wiestec i make desision for Stage 3 with TCM upgrade

the supercharger should be arrive in 2 weeks i will open my build topic here soon

CarHopper

Definitely need to upgrade the tranny if you have gone stage 3.

Also - what kind of stopping power are you looking for? Circuit track events, quarter, half, mile long drag events? DDing? What kind of driving are you going to be doing. OEM 2-piece brakes are quite able themselves and also adding bigger brakes adds more weight. It is also unsprung weight that you're adding so be mindful of that. I'm not entirely sure how it works but I think it is something like for every pound of unsprung weight you add 5 pounds of normal weight.

Well as for supercharger , in Russia there few stage 3 and with only tcm upgrade and still there is no issues as my local dealer and Wiestec says the clucth pack it self starts wear at hot weather temperature (trust me, this is not related to russia ) and very good traction on road such as glued 1/4 track or using slicks on car


For stopping power i mostly race "Roll racing" as for sprung rotational weigh i dont think 5 lb more weigh vs safety will be a comparing

i currenly dont feel enoth stopping power, as ask i thinking to go bigger and problem may be in my stock size wheels.....

CarHopper

390mm is a little over 15 inches so I think you'll be fine with the size.

However, if you seriously think you have stopping issues now then I don't think you should supercharge your car until you drive it around and get used to it. Adding bigger brakes isn't what you need, more time behind the wheel is. Because there is absolutely nothing wrong with OEM brakes.

Will those rotors play nice with your stock calipers or do you need upgraded calipers as well?

How will you fit those rotors to your stock calipers? Do you have adapters for the larger diameter rotors?

RacingBrake

We have a front 6-piton BBK (395x34mm) for Corvette C7 and Camaro with a fitment diagram below:



This template is based on RB calipers than stock, so you get some idea but can't be printed with 1:1 scale for try fit. If you like to do try fit, email us and we can send you .pdf copy that you can print and test.

We also offer 390x34 stock replacement rotor for GT-R (w/stock 19" wheels and Brembo 6-pot caliper), and they fit fine.

We are interested in developing those brake kits for Mercedes like we do for those American Muscle cars.

Here explains how RB BBK are designed and built assuring you the total integrity, compatibility and overall performance:

Surely would have to change calipers?

Stock Brakes are more than enough for stage 3.

I concur. People forget that these cars come with a monstrously powerful setup from the factory. A 6/4 front/rear fixed setup is no joke.

From all the spy shots I've seen thus far, it looks like the next W205 C63 is going to be "downgrading" with respect to the brakes.

Test mules seen thus far have always been seen wearing 6-piston fixed front calipers and single-piston sliding rear calipers. Why AMG. Why.

rear brakes do very little. Go look at lotus esprit. (i just bought one) The rear brake is a joke, the front is huge. Why bother adding unnecessary weight - not that it should matter since all benz's are fat cows as far as weight goes. As i mentioned in another thread. For the cost of upgrading to some monster 15-16" rotors which require new calipers. You'd be much better off swapping to carbon ceramics. For the price of those kits it's not much more. Ceramic rotors will last way longer. Like if you dont track your car, you'll probably never need to replace the rotors. You'll lose about 80lbs in rotational mass/unsprung weight too instead of gaining another 20+lbs over stock. You can even use factory spec parts too for all of it. Always keep in mind no matter how good your brakes are, if your tires can take it, it wont matter. Get some r888's on that beast.
