IndyCar veteran race engineer Bill Pappas will team with Graham Rahal next season at Rahal Letterman Lanigan Racing.
Pappas leaves Justin Wilson after two seasons at Dale Coyne Racing. Wilson was on pace to finish an IndyCar-best fourth in the standings, but was injured in the finale at Fontana. Wilson finished sixth - his best result in IndyCar and Coyne's best finish as an owner.
Pappas moves to Rahal, who finished a disappointing 18th in his first season driving for his father.
Pappas started with Roush Racing before Roush started in NASCAR. He then focused on open-wheel racing and worked for Chip Ganassi Racing, Walker Racing, Panther Racing, KV Racing and Coyne in a career that spans 25 years.
Pappas also did one season in NASCAR with Michael Waltrip Racing.
