Those milling around the pit area on Pole Day at Indianapolis in 1958 might’ve noticed a slim, slightly-balding, unassuming man posing with Jimmy Bryan for his post-qualifying photo. Bryan qualified seventh and went on to win the 500.

That man, Joe Sostilio, was a good friend of Bryan’s and an essential part of Bryan’s epic 500 victory. Sostilio was in charge of pit-stop preparation, and in an unusual practice for that day, he coached the team in a string of seemingly endless training stops.
