The EPA is asking Congress to amend The Clean Air Act to prohibit the racing of production cars, those built on an assembly line. That would leave only Nascar Cup cars, Indy, F1 and other races for tube frame cars. Please contact your Representative and ask him to support H.R. 4715 which does away with this nonsense. Please, this is no BS. It was on the Marlboro Raceway forum and we've checked and found it true. Thanks.
