International Race of Champions (IROC) was a North American auto racing competition, promoted as an equivalent of an American All-Star Game or The Masters. Despite its name, the IROC was primarily associated with North American oval-racing culture.
Drivers raced identically-prepared stock cars set up by a single team of mechanics in an effort to make the race purely a test of driver ability. It was run with a small field of invited drivers (6–12). It was created and developed in 1972 by David Lockton, the developer of the Ontario Motor Speedway, launched in 1973, with Mark Donohuebeing the first driver to win the championship in 1974. The cars used that year were Porsche Carrera RSRs. Donohue’s win in the fourth and last race of that season was his last win, as he died in a Formula One crash at the Österreichring in practice for the 1975 Austrian Grand Prix. The series was not run in 1981, 1982, or 1983.
In 2007, IROC could not find a sponsor and postponed the first two races at Daytona and Texas. IROC went on hiatus in 2007 hoping to return with a sponsor in 2008. In March 2008, IROC auctioned off its tools, equipment, cars, and memorabilia, and went out of business.
This was a great race series and with the build and tune the IROC Z was a little monster and a very strong car. You didn’t win because of the car or setup, team drivers literally picked car #s from a hat and out to the track you go, luck was not a factor although in some races one car was 2 mph faster but who knew? Teams didn’t know this when picking their ride, you’ll notice this in Al Unser Jr car at Watkins Glen. Some kart car racing also going on in the vid, the user was going between races the year is 1988. One thing for sure is that we don’t have HD in the 80s and little is documented of the series as in photos and vids but like many classics’ coming out of America the 1987 IROC Z28 is the shit!
From the user: IROC XII – The International Race of Champions, Round 4 from Watkins Glen International Raceway.
You will notice that during this video, whenever a commercial break happens, you will end up watching The Quaker State 500 CART race from Pocono for a couple of minutes. This right here is a classic example of what I had to deal with before dual tuner dvr’s existed and two races were on at the same time. Oh the hardship.
