ISCRA Sparco Pro Series

The ISCRA Sparco Pro Series is the second-highest tiered series of the International Stock Car Racing Association. Since 2017, the series has been sponsored by the Italian auto parts company Sparco. The series began in 1984 as the ISCRA Grand National Series, but in 1991 the series signed a deal with Permatex to rename the series the ISCRA Permatex National Series; after Permatex chose to not renew its sponsorship deal at the end of 2008, the series became known as the ISCRA Adobe Pro Series from 2009 to 2016.

Unlike the ISCRA Can-Am Cup Series, the series has opted to use a more unique points system which places an emphasis on consistency over winning. The winner receives 175 points, second place recieves 170 points, and so on; five points are awarded for a lap led, and an additional five points are awarded for leading the most laps of a race.

The series began as a sideshow to the Cup Series, running the day before the Cup race and oftentimes featuring Cup drivers looking to gain additional experience for the track they would run tomorrow. However, since 2009 the series has gone international, with races being held in Canada, Europe, and Australia in addition to the entirety of the United States, making it a challenge for Cup drivers to follow both schedules without making some sacrifices in the Pro Series; the most recent driver to attempt both schedules is Chris Howard, who will run both seasons for Steven Merzlak Racing in 2020.

Pro cars are currently prepared by the teams themselves according to a strict rulebook. These cars allow for a wide variety of rules packages that can be run at various tracks while still remaining cheap to build and maintain.
