Wayno;
Thanks for your comments; I thought about that but there is very limited space to enter/exit this cockpit so I have to be careful about blocking it any more than it is now.
My situation is not unique but the length of the shoulder straps from their attachment point to the point of my shoulder is very short- similar to most 'liners. This helps keep the body from much lateral movement (especially with a HANS device) and it is aided by the curvature of the seat which partially wraps around my rib cage up to under my armpits. Adding additional shoulder bolsters would be great but then I couldn't get into the car.
For helmet support I will fabricate two “arms” that attach to the firewall on either side of my helmet. They will be covered with energy-absorbing foam per SCTA rules. The outside one will be hinged so that it doesn’t hinder entry & exit.
My parachute was delivered yesterday by the Brown Santa. Now I need to design & fabricate a mount for the launcher.
