Rcx 6 lift vibrations?

[whonz]

I had more or less decided to go with the rcx 6 lift 1500. But now i read in their instructions and on their own website that the kit is not made for the AWD and would cause vibrations. How much is these and so on?
Have bilstein on 2.8 right now and think the vibrations is far to strong while 4x4.

I have the RCX 6" lift and 5100s set at 2.8 and i drove to work in 4x4 and no vibrations.
