It depends on what kind of car and racing you want to simulate. If yaw, under-steer or over-steer effects are not important, you can go with 2dof or 3dof. Motion platform which moves only the driver seats (2dof seat mover) offers the quickest response time and the fastest speed. If you want to move the whole rig, you will need a 3dof motion platform that offers bigger payload. If yaw (turning), under-steer or over-steer effects are must have you can go with universal 6dof motion platform or combination of 2dof seat mover and dedicated unit for under-steer/over-steer simulation.

You should be concerned about center of gravity and mass distribution, not about payload itself. Compare following 100kg blocks: 10x10x10 cm and 3x3x3 m. Any 100kg motion platform will handle first case, however second case might be problematic even for 1500kg motion platform.

Under-steer and over-steer is combination of yaw and sway. Both can be simulated by 6dof motion platform or specialized motion platform for under-steer/over-steel simulation.

For 2dof motion platforms you can use standalone multi-monitor setup or VR or both – it depends on your preferences. For 3dof and 6dof motion platform multi-monitor setup is more complicated to implemented. If you decide to have standalone multi-monitor, then you will have to limit motion platform operation range, otherwise users may not see screens in deep pitch or roll. If you decide to install multi-monitor on top frame, then it will increase required payload. It seems to be better to use VR for 3dof and 6dof with additional monitors just for spectators.

It depends on certification level you want to achieve with your simulator. If 6dof is specified as one of requirements for certification, the 3dof motion platform can be used for flight simulator. However, it is still recommended to use 6dof motion platform for heavier cockpit.

In this case there will be a heavy cockpit with high moment of inertia. It is recommend to choose motion platform that can handle 2x (twice) the real payload.

There is no universal answer here. Everything depends on what kind of testing you are performing and what ranges of movements you need.

You should be concerned about center of gravity and mass distribution, not about payload itself. Compare following 100kg blocks: 10x10x10 cm and 3x3x3 m. Any 100kg motion platform will handle first case, however second case might be problematic even for 1500kg motion platform.

Positioning repeatability is really high, the error is between 0.01 mm and 0.36 mm. It means that if the same test is performed many times, the result will be the same. Absolute positioning precision is combination of inverse kinematics precision and assembly precision and it might be up to a few millimeters/degrees.

Most of motion platforms components are already at least IP57 and we can galvanize all metal parts of bottom section and top frame. Please notice however that the power cabinet is not intended to be used outside, only motion platform base can be use outside.

Hardware: For PS series, our internal control board sends control commands to frequency inverters in ~4ms intervals. Frequency inverters reports current motor position in 10ms intervals.

PC: Usually there is no need to send control to motion platform more often than 20ms (50Hz) because frequency inverters need some time to interpret new requests. Current motor position reading is done in 10ms intervals (100Hz).
