Zimmerman rear rotors for BMW

This is for a pair of a rear base brake rotors for the following BMW models. Please pay attention to the date of the car manufacture. BMW Fitments: 3 Series: F30 (7/2014-2016) > 328i F31 / F34 (12-16) > 328i 4 Series: F32 (7/2015-2017) > 428i F33 / F36 (14-17) > 428i This was an incorrect part for me as the date of manufacture of my f32 is 3/2014. I learned the hard way. I installed the rotors and drove the car, but the parking brake could not engage, later I found out that the inner diameter of the rotors are too big (7.5) inches, compared to the original (6.5) inches. I ordered the correct rotors and installed it a week later. But bimmerworld would not accept them as return since they were used for about a week. I paid $186.30 for these rotors including tax and shipping. My loss is your gain. Here is the link where I purchased them. https://offerup.co/faYXKzQFnY?$deeplink_path=/redirect/
