I have them on my F10 and although I didn't have to pay the $9,200 option cost, I feel you get every bang for your buck. No brake dust to me is alone worth a large fraction of that cost, sounds petty, but true for notoriously dusty brakes. Also the fact that the rotors will last the lifespan of the car under normal driving conditions, and the pads will last twice as long as the standard is another offset in the initial cost. The squeal is minimal and not hard to get used to, especially when you and other car people know what you have. The gold calipers and curb appeal are another ✔️...the list could go on.
