Various safety items: 1)Reinforce battery and fire extinguisher mounts(use metal plate rather than washer). 2)Add bars to cage(1.5# per ft for .095) 3)Add driver aids(cool suit or helmet blower) 4)suspension reinforcements(sway bar mount or tie bars) You do note that most of these items can be mounted fairly low in the car. I forget where I got the ideas.
