BMW OEM G20 3 Series M340i 2019+ M Performance Rear Left Rotor 345 x 24 mm NewThis is a brand new genuine BMW M Performance 345 x 24 mm left rear brake rotor for the BMW G20 3 Series 2019+. Specifically, on the M340i M340i xDrive this is a direct replacement. If adding to a different G20 G21 3 Series then you will likely want the M Sport or M Performance calipers as well. This is the actual rotor that you get in the M Performance full brake upgrade retrofit kit that we also sell in its entirety in our eBay store. Thanks for
