I think they say it like, SM is Nat, SCCA written rules.
SMT and SSM are regional and what they want to do and so state what the regional rules are.
2015 Road Racing Schedule
Each Regional weekend will include two points races for all classes, equaling 14 points races for the year (not 16 as previously stated since the April 11-12 Majors does not count for Regional points). Eight races will be required to qualify for a series trophy. Exception: June 5-8 the SRF Festival Race will also count for points, giving SRF and SRF3 a total of 15 races (8 still needed for a trophy).

Was just saying to Ron yesterday that I don't really post here, just sit back and enjoy the show.
As I don't own a car anymore I don't think I mind what the tires are. What I will say is that it's a shame that the Sonoma weekend isn't over 4th July anymore. That's become my yearly race and I don't want to wait until September!
