I recently purchased a 2017 BMW M3 with only 50,000 miles. The previous owner upgraded the rotors to ceramic rotors, possibly with a 500mm size. After picking up the vehicle, I noticed significant shaking and pulling to the left when applying the brakes at around 60 mph or higher.

I took the car to my mechanic, and we thoroughly inspected the vehicle, ensuring that the rotors were properly secured — I have encountered similar issues in the past where loose rotors were the cause. The mechanic noted that the brake pads appear to be virtually brand new, suggesting recent replacement.

I'm reaching out to inquire if anyone might have insights into what could be causing these issues. I truly enjoy the car and would like to resolve the problem before deciding whether to keep or sell it.
