[QUOTE="MFE, post: 9115847, member: 36397"] Regarding failures, I think it's fair to note that Autopower bolt-in 4-points have held up admirably well in some relatively spectacular rollovers, where I'd rather have had one than nothing at all. [img]http://forums.corral.net/photopost/data/500/medium/roll_bar_crash_3.jpg[/img] [IMG]http://forums.corral.net/photopost/data/500/medium/roll_bar_crash_2.jpg[/IMG] [IMG]http://forums.corral.net/photopost/data/500/medium/roll_bar_crash.jpg[/IMG] That said, the possibility of punching through the floor bothered me enough after using one of these bars for 5 years that last spring, I added some reinforcement to the floorpan, tying them into the portion that creates the riser for the rear seat. That way the forces are distributed on two planes. So here's what I added to the main hoop mounting points. The 3 bolts in the center of this picture are where the holes are for the pads on the Autopower. I profess no more scientific rigor than "that looks like it has to be better", but I did use heavier steel than the floor of the car is made of, and I specifically tied it into the upright portion for the rear seat. It also overlaps where the subframe connector runs under the body. The panel is bolted, obviously, but I also bonded it with adhesive that you can't see under the metal. Looking straight down, facing the rear of the car on the drivers side: [ATTACH=full]1149095[/ATTACH] [/QUOTE]
