Same here, I`ve had a palstic RCI fuel cell in one of my cars for over 15 years, never any issues with the foam. The foam is still soft & pliable, and I`ve never found any foam debris in my fuel filter, pump, or carb. I`ve used nothing but C-12 for the past 9 or 10 years, before that I used a mix of Chevron Supreme 94 & Av Gas.
As for the foam having no purpose in a race car, it prevents sloshing, and would release the fuel in the case of a rupture much slower. Without the foam, it would seem that all you have is a weaker than factory container for storing fuel in the vehicle.
