Okay - here's something new and different...

I got the e-line OEM style rotors from R1 and the ceramic pads. They came in yesterday, and I'm putting them on today. I started on the drivers side, did the rear and everything was fine. Did the front, and I can't get the caliper back over the new rotor with the new pads. I pushed the piston all the way back. It's not even hitting on the pad - there's a little lip on the inside of the caliper that kinda raises around the pads, and the rotor is hitting that. Only way I could get the caliper back on was to switch out the outboard pad with the old one. Once I did that, it fit no problem. Do I need to grind down the new pads to get them to fit or what?
