The chassis is from plain circuit board, it is epoxy with a copper layer. The copper layer is not touching the batteries.
Regarding the bodyclips, as you have mounted it I know but the clips still are under the rear wing, this works fine for me.
The tires, they are not foam but rubber, the "damaged" sidewall is just some graphics on te side. Grinding down is also no option....
