Quantum duct inlets with a BBK

Track Monkey
Has anyone installed the quantum backing plates in addition to a BBK? When i installed mine a few weekends ago, the plates were rubbing on the rotors so I removed them. I was hoping to have more time to play around and see what I could do to make them fit, but I'm busier than I expected. I wont have much free time before my next track day, so I was hoping to have a plan of attack for the next time I try to get them hooked up.
