2018 Rule Discussion


Staff member
The official rule discussion for 2018 is open. Please remember to consider what is best for the entire class, not just yourself. If you have raced an TSM event in the last 2 years you have a vote.

Thanks to all the racers that make this class great!
Looks like things are staying the same for 2018. No one has suggested anything. I will leave this open until January 12. If nothing has been suggested by then the rules will be closed until next year and we will run with the same rules as 2017.
Paul, one thing I think needs to be addressed is the throttle body rule. Presently it states a max of 70 mm when the GN1 Performance TB is a 72 mm piece and I am sure some are using it. I do not think this needs to be voted on as 2 mm at the TB is not going to make or break any ones combo, just needs the wording changed.
I'm curious as to how many cars in the class actually run dual pipes to the rear? If I recall some only have 1 and others removed theirs at the dp.

That could be a discussion for next year. Got to keep in mind the true heart and theme of the class though. 8.50 is obtainable with our current rules.
