    Welcome to the club Rory,

    I BELIEVE you'd be in STS, someone else should chime in here.

    In STS you can also run a modified exhaust (even headers), you do need to run a cat though.

        Hi Rory,

        For the remainder of the year you will be classed as a Novice. If you participate in 3 or less EVENTS (not runs) this year, then next year you will be eligible for the Novice group as well.

        Novice drivers are not permitted to have a passenger ride with them. The only exception is a senior driver can be a passenger.

        We look forward to seeing you at the pad!

          If we are going absolutely by the book, potentially your Momo steering wheel might not be STS-legal. According to Section 14.2D of the SCCA rulebook:

          D. Any steering wheel may be used. An alternate steering wheel assembly, including all mounting hardware, which replaces an airbag-equipped wheel is not required to have an airbag but must weigh at least as much as the standard assembly. An alternate wheel is not required to have a horn button.
          So depending on whether your Momo steering wheel is heavier than your stock steering wheel, it may or may not be STS legal. For local competition, someone would really have to be an a$$ to protest you on those grounds. But FYI, it is something you should know about, and I have been told that at the regional competition in the US, someone has protested a winning Canadian-spec STS Miata because the Canadian and US cars have slightly different steering wheel, and the rulebook at the time was written without allowing for this difference. The Canadian car lost the class winner title because of the protest.

            Somewhat off-topic, but a good reminder that at big events people do care. Local events.....not so much.

            Assuming we are thinking of the same incident.....

            Issue was that a 1990 Canadian Miata did not have an airbag steering wheel. US cars did. Rule was that an airbag wheel could not be replaced - a non-airbag wheel could be replaced. Not knowing the difference between the Cdn Car and the US car the owner replaced his factory non-airbag wheel in good faith. SCCA rules are of course based on US production. Cdn car won STS and was protested and disqualified. Innocent bystanders who know a thing or two about Miatas pointed out that the now winning (originally second place) car was in fact illegal as well due to the missing front tow hooks (baby teeth in the Miata world). Somewhat of a weenie protest, but many believed the original protest to be poor sportsmanship considering there was a substantial margin of victory. The former second place - now winning car was also disqualified. The originally third place driver sat quietly by until the smoke cleared at which point he was awarded the trophy and the contingency winnings.

              ^^ Yup, pretty sure we are thinking of the same incident. Just goes to show that some people really take their racing very seriously, esp at the bigger events.

                People do weird things when money is involved.

                Most important thing is that would never happen at local event, run STS and have fun.
