Howdy,
There are two sheet metal panels (about 12" x 12") under the car I had to remove to get the C4 out. The body nuts are rusted and broken loose.

Question: Are these panels a must or can I leave them off? Maybe I should tack them on/ Are they just for body stiffening or do the coupes have them too?

Thanks
