Rear caliper upgrade

[Neilb76]

Has or does anybody know of you can change the rear calipers. I like the msport rear calipers as they look better And bigger than the standard m5 calipers

Brembo big brake kit. However, you lose the parking brake

That's a good point

[Mazing81]

Does anyone make a bracket for a Panamera caliper?

You should not just slap on a different caliper for one end of the car. That will alter the brake bias, which has to do with how much force is being applied to the pads front compared to rear unless piston area remains the same (unlikely). There are other considerations that I won't go into here (including rotor size). The point is you need to treat your braking system as a system rather than swapping in/out individual parts. If you mess with the bias without knowing what you are doing exactly, you need to get ready for some nasty surprises under hard braking.

The stock brakes are sufficient for this car and the braking force is mainly on the front rotors. I don't think you are using a car on a track. For city driving and fast driving, it is enough, but if you want a significant difference in braking then you need to put on the ceramic brakes.

[lucid21]

Ceramic rotors will not make the car stop better. They will lower unsrpung weight though, which is good for handling. The main limitation/factor in braking is traction (friction between the tire and road surface). Creating high friction at the pad/rotor interface is relatively easy (can be adjusted with pad compound among other things). Caliper design mainly comes to play for applying uniform force onto the pad to maintain optimal pad/rotor contact/pressure. So, if you want your car to stop better, first invest in tires, pads, downforce (for high speed braking), and then start to mess with brake bias to make sure the rears are utilized to the limit (which is not easy to do, so I would leave that alone). All cars are front biased out of the factory because that is where traction is under braking (when the load on the front tires increases) + plus too much rear bias can make the car unstable. Under repeated braking, fade considerations apply and that is mainly handled through increasing the heat sink (rotor) mass and directed rotor cooling.

ceramic brakes stop the car better and can repeat stopping continuously. Regular brakes will overheat and lose traction after 2-5 extreme braking. Seriously someone is not enough rear brakes on the M5? for some reason I think it's just how they looks poor 🤣

[Yan228]

it is expensive, it is necessary to service the carbon rotors, to flash the car under the CC, it is inappropriate for the city.

Don't mess with the stock brake system, if you want to upgrade then upgrade everything

Sorry but this is just not true. You need to look into the physics of braking. There is nothing magical about ceramic rotors. They are a heat sink the iron ones are. It depends on the thermal mass and some other variables that I won't go into here. Cool thing about them is that they are light. And they are supposed to last for a long time (which I have not seen any data on).

Almost 100k city/hwy driving on my CCB's. The braking with them feel a whole lot different than my buddy's M6GC. I know it is not empirical data but you'll quickly know/feel the difference between a like car with and without. It is very noticeable between my wife's 550 and my m6. The lack/low collection of brake dust with ccb's is almost worth the price of admission alone. The cost of pad or rotor replacement is not for the faint of heart though.

[lucid21]

The "feel" may very well be better but they just won't make your car decelerate better (which is what the poster insists on). They do have some heat dissipation benefits but nothing that can't be managed by forced and directed cooling on the metal rotors. I do envy the lack of dust feature though. Pain to constantly clean the rims...

[M5Rick]

When they are working fine ccb's perform well but there have been instances where for no reason a chunk comes out of a disc warranting replacing at crazy price, also removing a wheel requires special handling so that a rim doesn't catch edge of the very fragile disc and though they are reputed to last a long time discs and pads will require replacing eventually when a mark starts fading on the discs.
