Ok guys, within the next year I will be needing to do something for a little piece of mind for the GN. I dont race the car but it will be doing some Autocrossing and an occasional weekend at the track but mostly just a street car. My main problem is the crossbar that goes across the back seat. I know I can make a removable bar across there but is there any way to get a certifiable cage with that cross bar running on the floor board just in front of the lower seat cushion? I really dont need the cage to be certifiable but I'd like to make it if I can. Any ideas? -----Jeremy
