Personally, i think that Dyno tuning is already in the minds of the modelers and that stuff. Second, I like the Class S idea, is a bit complicated for you, NFSSA team to do but it's just awesome. Third, 8 players races is already posted (1 year ago, LOL) and that means Underground Racing League (most known as URL). That is my complete opinion of your post, even you commited a grammar error (Spoiler, no alerón one).
Always aspiring for the best of myself! ^-^
