I created a seatbelt attachment point to the motion actuator foot and provide tension while driving. Recommend crossing the belts behind the seat so you can feel the tension in opposite shoulders using a bungee cord.
The hole on the bottom of the block is slightly larger than the E-racing Labs foot so that the rubber of the motion system still sits on the floor and you don't have to worry about the print being able to support the weight. You may have very slight movement of the block during use, but should work overall.
Use caution lifting and lowering the sim rig and attaching bungee cords.
