since someone already posted that the 5 series brake calipers fit our cars, along with the 395mm wopping big dimpled and slotted 395mm discs

I was considering this upgrade but didnt want the extra weight of the upgrade, and was willing to wait until the aftermarket caught up with 2 piece units.
but was looking and waiting and saw Alpina is offering these 2 piece units that are stock on their B3 cars and im assuming it has a part number associated with it.
with actual holes instead of dimples and the 2 piece aluminum rotor design, i'd figure it would weigh as much as the stock m-performance discs.
Even the rears get the cross drilled action but this pic of the configurator is all i could find on the rear. and THAT also looks 2 piece as well. could these be re-branded next gen M3 discs with just the alpina logo? ( looks like the next gen m3/m4 will have different calipers though)
