I'm planning for the 2014 season, to try to qualify for the Runoffs @ Laguna Seca (I'm an SF Region driver). I race an ITA prepped RX7. Just for clarification, if I leave my car alone (it is ITA compliant) do I need a fuel cell and the cross-dash rollcage bar? Reading the GCR, it's not exactly crystal clear. Thanks, in advance!
