If i remember correctly, back in the day, everyone running alcohol had to have a /15 fire suit, but NHRA and other sanctioning bodies let that rule slide because so many people were running slower cars on alcohol. I have an almost new /20 2 piece suit, and i've been trying to lose weight to get back into since i went from a Med to a lg. I don't need a /20 only a /15 but figured i could save the cost of buying a new one. The /20 may be for sale, since it's looking like i'm not going to make the weight.
