I need a replacement left rotor for my '07 Norge, and in doing a general search I noticed very few sets (left & right) come with the pre-drilled holes on the right for the ABS ring (or is it a speed-sensor ring? Same thing?). I also read a cryptic post about their being a "fix" with a different sensor ring that can be used with EBC rotors.
What are the options to be able to retain the factory ring? Or different ring? I actually only need the left-side, maybe a used pair or left-only on ebay?
