I have chassis about done and finalizing few thing. My seat has 1" bar across front(at uprights) and the rear rest on rear bars.This is raised seat chassis.The seat it self does not have any bars under the butt. Do I have to have them? Seat fastens to 4 places attaching it to chassis and upper section. If have to have are moly straps suffiecent.1"x .090? I may also be making carbon fiber one piece seat later. Oh yea building to 2.2c spec on everything else,so might as well meet it here also. Could not find it in specs but then I am bad about reading over stuff at times.
