Question Looking for advice on construction of Seat-based Traction-Loss

    After exploring options to add a TL-construction to my rig, I have ceased the idea due to limited space available. Alternatively, I am now looking into options using a lazy Susan below my race seat to give me TL.

    I am looking for advice on the following questions (illustrated by attached picture):
    • A: where best to locate the pivot point of the lazy susan?
    • B: does the distance between the two pivot points (lazy susan on one side and the pivot point of the linear guide stage rail on the other side) have any impact on the functonality of the traction loss immersion?
    • C: does stroke matter and if so, is larger better? My assumption is that it doesn't have to be a large stroke to give one the correct TL "feeling". What stroke would you recommend?
    • would it make sense to built in an opion to move the lazy Susan below the seat to explore best pivot point and if so, any suggestion how this could be done?

    Just to be clear, if the rotation point is below the seat the axis will be yaw, while TL has the rotation point forward of the seat, normally around the feet. The effect of each is not the same.

    Thanks for your response! Independently of the name, that would make literally most TL installations on sim rigs to "yaw" builds, as most TL pivot points are in the middle of the rig (so slightly in front of the seat).

    The big difference I see is that with a platform TL, your feet/pedals also move in the direction of the front, which does not happpen with a seat TL.

    May I conclude that in your opinion, a pivot point as far forward as possible in front of the seat would give me the best traction loss immersion?
