Greetings

I’m visiting from the G01/G02 forum where I’m quite regular. Am very close to upgrading my current brake system with the G05 M Performance BBK. I’ve been assured that it’s a straight bolt on to my 2023 X4 M40i. My only hesitation is just how much heavier the rotors will be


The BMW part number for the kit is :

34-11-2-458-883

The part numbers for the front rotors :

34106887657 34106887658

The part numbers for the rear rotors :

34206896221 34206896222

I’ll search this forum further in case this information (the weights) has already been posted

Any insight would be greatly appreciated

Front rotors weigh 39lbs and the rears are 26lbs
