Instead of writing to anyone in SCCA about legality to find out if your interpretation on whether something is legal or not you have to do it. Then have a friend protest you, then after it is decided at that particular event with those particular stewards if it is legal or not you need to have the party that the decision was made against appeal the ruling so that it is a appeal/ruling that ends up in Sportscar that you can take to any track with any Stewards. Yup that is a run-on sentence for a run-on system...
