If such test is conducted, it would be interesting to see whether the M2C can stop in a shorter distance than the M2 even with the larger brake, assuming they are wearing the same Michelin or Conti tires with similar tire wear. I would actually consider the M2 a small favorite in such test. In either case, I doubt the margin will be significant enough to be of any relevance.

I get what you're saying; I am always braying to everyone that that tires are the only part of any vehicle that actually touches the tarmac, regardless if it's a Bugatti or Honda.. However, the M2C is heavier and more powerful vehicle, so the BBK are welcomed, regardless of how adhesive the tires might be.. |

I honestly can't recall coming across any F10M showing the discoloration. I've seen it on quite a few M2/3/4 and it's caused most of the time by running the pads too near the wear limit on the track. Also have come across a few where the bleeder nipple leaked, and also from leaving solvent cleaners on the surface and allowing it to get hot. |

Discs are so much heavier rotational weight goes times 9.
If youre discs are 9kg heavier it feels youre carrying an extra passenger! And most trackday tires are 18 inch. You can better spend the money on an ap brake set and lighter discs then this very heavy system. It looks nice but it drives worse! |

So what do you think a comparable, lighter AP Racing BBK would be and would cost? |

If people want to save weight because of rotational inertia they should not opt for wider (heavier) tyres as tyre being furthest out to the centre of the hub has the highest multiplier effect. The slight impact in handling is a fair trade off for a greater heat dissipation ability from the big bake system. |

I suppose your new rotors are quite for now, because they are not worn in yet. BTW, I switched to PFC08's recently and am not a fan. Not sure why so many love them. I think the Hawk HT-10's have way more bite. I guess it differs depending on driving style. Quote:
Also, calipers, which are part of the weight gain of the bigger brakes, aren't part of rotational mass, obviously. |

I don t get why will you put 17kg more weight on youre performance car. It s the wrong way around.
I drive with pagid yellows allround and have no problems. Brake hard and short. And after 5 hotlaps i do a cooling down lap. I have had zero problems and don t need heavier brakes for sure. It is a nice option for the posers. |

After track usage, I'm pretty sure we're going to hear stories like "My Red BBK are now Hello Kitty Hot Pink"

From what I gather, the only point of a BBK is for increased cooling (besides aesthetics) - wouldn't a brake duct produce the same, if not superior, effect? As others have noted, as long as ABS is kicking in, your limitation is your tires, not your brakes?

I do track days, certainly not as much as others here, but I'm out a few times per year. Like others, I have been very pleased with my factory brakes, with the mandatory pad swap and fluid upgrade. My question is this (provided that I have driven the M2C exactly as many times as all others here...), aren't we likely to REALLY appreciate the BBK as we try to slow the heavier car coming into corners carrying more speed (S55)? I'm really hoping the new power gets us moving faster despite the added weight, and the BBK will end up being an appreciated upgrade.

With a BBK you have the extra cooling capacity plus the extra mechanical leverage from clamping the bigger pads onto the bigger rotors so you don't have to work your brakes as hard. Therefore it has a higher tolerance against brake fade. In addition all the auxiliary parts (pistons, rotors, pads, brake fluid...etc) will last longer. |

It’s a necessary evil for those that truly need it so I am not speaking against it universally. I would just recommend that one should exhaust other brake improvements that do not incur weight penalty before resorting to larger brakes. So often people automatically attribute brake mushiness to overheated rotors, when in fact the causes are overheated brake fluid and brake line expansion. OEM brake pads are typically of low quality (or designed for street-ability) because they don’t meet the eyes and don’t cross the mind of regular car buyers. Upgrading those three things on the base brake kit should provide ample braking performance except for truly hardcore track drivers on demanding tracks. It’s easy to overlook the base so-called “M” brake kit is already a BBK in itself at 380mm (15”). It’s used on M3/M4 that has an even higher powered S55. I suppose it’s all moot if the larger brake kit is indeed standard on the M2C. I just think it should have been a $1,000 option instead and lower the price increase from $4,500 to $3,500. And, yes, people should also not get wider tires than what the car needs. It’s a balancing act, like everything in life.

Also, people are quoting the increase in "brake weight" and assuming it's all in the disc which is of course false.
