Please take a look at this thread - https://g20.bimmerpost.com/forums/sh....php?t=1742610

Yes, based on my search on bimmercat, the M340i and 330i share the same parts for the MS brakes:

1) the 345mm MS rear brakes - https://bimmercat.com/bmw/en/parts/i...4081/appliance

2) the 348mm MS front brakes - https://bimmercat.com/bmw/en/parts/i...1283/appliance


Please note if your 330i already has the MS brakes (blue 348mm/345mm), you can also upgrade the fronts to the blue 374mm (M340i ZTK option) brakes - https://bimmercat.com/bmw/en/parts/i...1303/appliance

Thanks man, super helpful!

I don't have the MS brakes as an option, I just have the standard disc brakes on an xDrive. I'm just on the fence whether I should upgrade to the MS option brakes or the MP BBK. Also trying to understand what the costs are on the MS option compared to the MP BBK. Obviously the MP BBK is easy to find the price, but the MS option isn't readily available and still unclear all the parts needed to convert it.
