Supersprint interior panels

[Olgawld]

Hi. I've taken the interior panels out to take a better look at the chassis grot areas and give a good clean out. Was surprisingly pretty clean actually. Anyway I'm now liking the look of it without the panels. My car's bare ally so I'm liking the stripped down interior look which kind of matches. I'd already removed carpet in footwells and tunnel

Question is, is it ok like this? Do the panels and the honeycomb crash protection really do much. Someone's suggested it's there to help with chassis stiffness? Car's only for road use. Anyone else done similar or know if it's ok like this? Thanks
