Hey @whaletail, come back and share how you get on. Steel plate around 4-5mm can work quite well with the units attached to this with then isolators below on a supported upright. You may even want to use a thin layer of rubber material between the unit and the steel plate. People in the past I helped with 80/20 found good results with something like this: Steel Plate with Rubber Layer / Tactile Attached / Isolators / Support Upright / Main Cockpit Frame / Isolators / Floor Isolators can greatly improve how the tactile will feel and help maintain it in the frame, no question about that. Having the tactile pass into the pedals/seat regions prior to it being able to travel in various directions could also make a difference too. Various things are worth trying especially with 80/20 being easily altered. Im keen to learn more of the BST-1 abilities if you get around sometime to testing or giving your views on it. @SOLO59 and further updates?
