This new brake are just add of weight, lost of tire size (18 inch) and no more than half lap of durability.
Talking of road use will be worst for noise and more fuel consumption.
Basically a waste of money. A real upgrade was if they develope with Brembo a small ccb system, lighter and with 18inch rims

I think the big brakes looks good, but I am a bit concerned about the additional weight.
Stock brakes:
Stock front caliper 4,89 kg, disc 11,29 kg. Rear caliper 3,6 kg, disc 9,25 kg
Option front caliper 7,54 kg, disc approximately 13,8 kg. Rear caliper 4,3 kg, disc approximately 11,3 kg.

If my assumptions are correct, it all adds up to 15-16 kg of unsprung mass. I am considering not to add this option… |
These new brake are + 15 kg of rotating weight
Ccb are -13,5, the difference is very high! 27/30 kg so no sense to spend more money for increasing of weight and maybe half lap of more resistance on the track. After that spend 10000 dollars for carbon parts to go at same weight.
This m performance pack is a fake!!!
