So the car is in the hand of my indy and we called BMW to find a caliper and bracket only to find them completely useless. They keep telling us the X6 never came with a dual caliper but when I search online I am able to find it. They even have the same casting numbers on it.

Amazon.com: Centric 141.34112 Front Brake Caliper: Automotive

Anyone have any clue where I might locate the bracket?
Any change the stock bracket is compatible? I didn't really look at them I just assumed the dual piston caliper wouldn't work. Yeah that is just wishful thinking.
