'11 Front Pads and Rotors - a/c delco?

[schneids33]

So we bought a used '11 x35d and it's finally out of warranty. First big cost is going to be the front and rear brakes being done. As you can guess the BMW dealership was stupid. The BMW specialist was a little less stupid and the local repair shop was not as stupid. The BMW place uses OEM parts and wants $770 to do the work, while my local shop will use A/C delco parts and wants $440. Even if I bump up and use some different parts aftermarket parts like brembo etc i'm in the low 500s.

The question is, should I worry about using A/C delco ceramic pads and rotors? I have them on my '12 mini and haven't seen any issues.
thanks
