ECS makes a bracket for the rears but they won't sell it individually, spoke to customer service today. They want a ludicrous amount of money for their kit.

Apparently they mill the rear calipers and with their proprietary bracket the F80 m performance kit works perfectly. I just can't justify spending that kind of money when this kit can be had for far less $$.
Looking at their price, milling the rears on your own and going with 535 rear rotors seems the way to go. I really think ECS makes a high quality product, but this is a little ridiculous. Why not make this bracket available?
