The rear brake rotor I used the 380x30mm rotor from the front standard brakes of M4/M2.

Using some educated guesses on where they are getting the parts from. They certainly aren't sourcing all new rotors. Even if they did, they each would be within 1kg or less of what I have listed. 30lbs increase at the minimum, but I think 35lbs is right on the money. |
I just did the front and figured out the total area of just the brake rotor without the hat. Then calculated the volume for that vs stock brake and got 15kg. My way isn't 100% accurate either, but if you split the difference, yes you're withing 1kg.
Think that's as close as we're going to get until the official tech specs are released.
