Similar to the yellow Corvette (?) above..
If you strike out with the belt material you might check auto parts stores for a medium-density polyurethane foam floor pads.Over here,they come 5-panels per package (610mm X 610mm) for around $15 (US).
I've used the same foam on my truck at least 3-years now with little degradation.
At 75-mph there is no deflection,while if I hit a curb they just bend under until I back away.
Kind of a medium-gray color
