So the new rulebook released on June 24th now allows us to change out charge pipes and blow off valves in Street Touring Hatchback (STH) class- this could be useful for those that have these parts and want to run in that class.
I couldn't find any other changes from the previous rulebook for that class.
The rules can be found here: https://www.scca.com/pages/solo-cars-and-rules
