Junior Johnson's "Banana"  

Speking of cheating, I had a book about the 60s and 70s of Nascar (can't remember the title). My favorite chapter was on Jr. Johnson's Ford Galaxy # 26 painted yellow in the, I believe, late 70s. The car was dominating the 1 /1/2 and larger tracks.  Nascar suspected something was not legal with the car but they couldn't put their finger on it.  Junior was finally "busted" when Nascar determined that the car's trunk lid was slightly bowed up giving the car added rear downforce.  Keep in mind that they didn't run much a spoiler back then.  Junior said that he named the car the "Banana" given its slightly curved shape.  Scott Ely
