Vibration reduction

I need your help to know how to reduce the vibration on my quad. I’m trying to get the ±3 on AccX and AccY and +5 to -15 on the AccZ axis.

I reed all the documentation regarding the vibration damping but I’m still near the limit on the Z axis and I’m ±5 on the X and Y axis. See my log attached for a detailed view.

I tried, double sided tape, 3M foam and finally I got the best result using 2 pads stack of Kyosho gel. But there is still place to improvement.

I’m wondering what result I could expect knowing that I’m using the F450 frame, Turnigy rotors and Turnigy carbon fiber props?

See my quad configuration :

Thanks in advance for your help

Hard to see if it’s this but is it possible that the wires and other stuff in the area are touching both side of the frame and the APM? If they are then the vibrations could be coming through the wires. Make sure that there is plenty of room between the wires (or any other item) and the APM. I had this problem with a 250 sized quad.
