    rubber, poly or solid mount for the motor tranny/xcases. what would be the best way to go with a 350, 400, 203-205 set up. just for reference my rig has the cage tied at 10 points and i was thinking on ditching the rubber or poly mounts and mounting everything solid to the frame. am i asking for trouble?

    Solid seems like the way to go if you have zero frame flex.

    They do transfer alot of vibes from what fulltop told me about his.

    But in your case it might just be easier to swap in poly motor mounts.

    Me personally I think a little movement would be good so I choose poly. I know solid works because a lot of buggies go this way, but I think eventually something is gonna give, and i dont like the idea if an adaptor being the weak link.

    yeah, I'd be worried about the adapter and trans too... cast stuff tends to not like flexy frame action. IMO, if you decide to solid mount the engine/trans, then definitely do everything humanly possible to make the frame super rigid. Tie in the cage, box it... whatever ya have to do. On my truggy I'm gonna try going with all poly mounts.

    Going solid is asking for big trouble. Use poly, especially in places that dont require a lot of flex.
