If you are building the RS1 simulator with the triple monitor stand then you need these heavy-duty rubber feet. These feet are made of natural rubber and raise the cockpit off the floor to allow ventilation to any components underneath. These taller rubber feet are ideal if your RS1 simulator will sit on carpet since they provide the additional height necessary in that application.
If you are adding a Buttkicker transducer
, Bass Shaker or any other type of tactile transducer, these rubber isolation feet will separate the vibration from the floor and makes you feel more vibration than if the simulator was sitting directly on the floor.
