Re: Roll Bar/Cage
IHRA used to require a 6-point cage at 11.49 versus the 5-point for NHRA, but I don't know if they changed it in the last few years and CFR switched from IHRA to NHRA. You could just not weld in those extra 2 legs, most the kits I see require welding of those on. I don't think they are for any rules, just for chassis stiffening, since the next step up in rules requires a full cage with halo. A full cage does use those 2 points, and you could convert to a full cage, but you can also run smaller diameter piping when doing a full cage versus a roll bar to save weight.
