I 'll be upgrading to X5M brakes soon. I bought the calipers used on ebay last year but then ran into some issues when I purchased after market rotors from brakenetic.

I just purchased OEM F85 Rotors albeit at double the cost of the brakenetic ones, which is why I waited so long to get them. They should be arriving today.
I'll be reaching out to hardparker for the bolts and spacers and will start a new thread with pics once they arrive.
