The rules are generally the same, with most differences being that we offer a bunch of classes not, as I understand it, found on the Salt. I don't think SCTA has Circle Track classes, or some of the street car classes that we offer. When you get your ECTA book, a lot of the drawings, etc, will look very familiar if you have an SCTA manual. Always best to get the rule book for the sanction that you're running. Years back, I had a bad experience when going from an AHRA (remember them?) track to an NHRA track - almost the same, but different.
