Oh and to comment again how much force went into my car to make that little dent, it completely pulled the cage out of several reinforced sections of the floor pans around the car... literally tore the car apart but kept what was inside it straight (ish)
Dan, did you remove the std seat mounts/lateral floor bracing?
Just wondering if it would've helped at all.
I'm considering doing the same to one of mine (deleting seat mounts) having seen the photos I will definitely be adding low level cross bracing to my planned cage!
