American Endurance Racing AER - 180TW tires

Champ Car Endurance Racing - 180TW tires

24 Hours of Lemons - 190TW tires

NASA PT, SE30, 944 and SM Classes - Significant penalty for 40TW tires/Toyo spec tires/Toyo spec Tires/Mandated Hoosier tires but the price is significantly subsidized and their contingency is good

Why are they so successful despite their lack of organization and structure. What did the SCCA (and MCSCC) miss? What happened while we got so comfy?

(Probably just coincidence)
