A road course ringer, also known as road course specialist,road course expert, or a road runner, is a non-NASCAR driver who is hired by a NASCAR Sprint Cup Series or Xfinity Series team to race, specifically on road courses.
Current NASCAR national-level road courses include Sonoma, Watkins Glen, Road America, Mid-Ohio and Mosport. Former road courses include Riverside, Topeka, Mexico City, and Montreal. Typically, only two or three races a year will be a road course in any of the top three divisions, providing limited opportunities for ringers.
NASCAR describes road course ringers as "drivers who specialize in turning both left and right," and says that "perhaps the greatest road-course ringer in NASCAR history might be Dan Gurney" after he won four straight NASCAR races at Riverside. He lapped the field at the 1964 event.
"Ringer" is a slang term commonly used in sports to describe a particularly good competitor who is brought in to win in a specific match as opposed to competing in the entire schedule. It can also be used to describe a professional athlete who competes in amateur sports; a softball team might have a "ringer" who used to play minor or major league ball. The term does not relate directly to racing and does not refer to the shape of the race course.
A road course ringer is often brought in when either the normal driver is inexperienced at road courses, or if the driver is having a poor season and the team needs an excellent qualifying run to qualify for the race.Sprint Cup Series teams who are near the bottom of the top 35 in owner points hire a ringer or adept former competitor like Terry Labonte to ensure that they remain in top 35 to keep a guaranteed starting spot in future races. It is not unusual that a lower level team's best finish would be at a road course because of the use of a road course expert. Some full-time drivers are adept at racing on road courses, but they are not considered road course ringers. Road course ringers have competed in championships which race primarily road courses, frequently in IndyCar or sports car racing series such as ALMS or Grand Am.
