When we want the camera rigged inside a vehicle we combine different tools and items to rig and fix camera heads, sliders, tri-hats, bazooka bases, etc. Also riggings just for the camera with no head to get the most of the room we could have. We can use half bowl system heads, rocket plates, etc. in order to operate and correct the frame. We can make the camera support rock solid and safe for action driving.
For simple camera set ups we can use our lightweight rigging system getting attached to the car by suction cups, and all kind of starters made by GS.
