SFI?
For one thing.. it would have to be a rag top or a altered dragster... and I dont know of any guy that thinks of their race car like a piece of trash to be UNCOVERED OUTSIDE... the sunlight is what I THINK they are concerned with... but maybe just rot.. JMO EDIT in reality they should take 100 pair of nasty looking 5 year old belts and give them the SAME test.. show the data
