SEMA says the EPA is trying to pass some legislation that would make modification of street cars into part or full time track cars illegal.

“This proposed regulation represents overreaching by the agency, runs contrary to the law and defies decades of racing activity where EPA has acknowledged and allowed conversion of vehicles,” said SEMA President and CEO Chris Kersting. “Congress did not intend the original Clean Air Act to extend to vehicles modified for racing and has re-enforced that intent on more than one occasion.”
