Noise when turning and braking at low speed
Recently I've been hearing a pretty loud noise almost every time I turn and brake at low speeds. It happens when pulling into a parking spot (to the left or right) and I captured it on video while pulling through a drive thru. I thought it might be a brake dust issue, but it happens all the time, even after cleaning the wheels. I did recently change to 437M wheels and don't remember hearing this, at least not this loud, until after changing out the wheels. The car is a 2017 F36 with 32k miles. It has the M-perf "blue" brakes that come with the track handling package. Brake fluid was changed and the brake pads/rotors were inspected at 30k miles by BMW in January as part of their CPO conditioning. I do get the "normal" squeaky brakes when they are cold, but they function normally and quietly under all other conditions. Any thoughts would be appreciated.

That sounds like a sympathetic vibration. I'd try re-lubing the pads, carriers and calipers, and checking the torques on all the brake components.

Unfortunately no. When I took it in for service at my local dealer, I mentioned how noisy the brakes were. They took if for a test drive and said there are "hot spots" on the rotors. They quoted me $2600 for a front/rear brake job. F that, so I searched the forum and ordered new Hawk pads and StopTech rotors. I'll get them installed at a local independent shop.

I love these dealers who tell you that you need a $2600 brake job instead of $3 worth of brake grease. BTW, hot spots on rotors, aka heat warp, cause brakes to pulsate. They don't cause noise. His shop must be on a very long stretch of straight highway to see you coming from so far away.
