With the rear grill side) fazors, how did you attach them? I assume some type of double stick tape, but did you put tape under each fazor "vane" ... or just edges I am curious because I would like to secure them so that there is no chance of vibration or resonances. Same question with the pad side? It seems some have just used tape under the "wings". Does that allow for good contact with the flat part of each vane and the magnet. Same concerns here. I would like no chance of unwanted vibrations, and to ensure smooth air flow without gaps to add turbulence.
For both rear and driver side fazors I've used thin double-sided tape. I put the tape around the perimeter of the fazor and on every second "vane", it stays in place and I did not experience any vibrations/distortions. After removing felt strips there was sticky stuff left on the driver metal grills, spent quite some time removing it so there would be no gaps when a new fazor is mounted. Fazor is sticking out a bit and pads do not hold in place as securely as without fazor though. I've used new layer of double-sided tape, but still can see gaps between pad and headphone appearing after some time. It is not so bad that they would come off, but I would like them to be more securely held in place. Maybe when I'll get new pads I'll use stronger tape.
