im sure it does something, but it hardly does anything. eventually im going to cut down my bud built and make it so it mounts onto motor mounts on the inside of the frame rails, the same way the engine does. with the mounts slanted the same the way the engine mounts are set up. 1 mount on each side of the frame for each side of the crossmember. that way there wont be any vibrations and i can still use the solid mount i made, and the budbuilt will mount with typical toyota motor mounts. the engine and tranny/tcase would be held to the frame with 4 motor mounts total, i think that would be kinda cool.
