Quick question for you guys from an 818R builder: Have any of you encountered any race sanctioning regulations or tech inspection issues concerning the aluminum floor footbox panels in the challenge series?

The 818R has a steel panel welded in, but it's warped and pops up and down due to the heat from the welds. I'm thinking of cutting it out and riveting/fastening an aluminum plate for a footbox floor panel, probably something thick but no thicker than 1/8". I just want to make sure I'm not screwing myself by doing so.

Thanks!
