Racing history
On 15 November 2012 the Supercar Challenge organisation in conjunction with Praga Racing and Radical Benelux launched a new racing class.[4] The Supercar Challenge Superlights would feature four sub-classes, one for the Praga R1, one for the Radical SR8, one for the Radical SR3 and one for Group CN cars.
2013
The first race of the Superlights class was run at the Slovakia Ring. Praga Racing announced that they would enter 10 Praga R1's in the first round. Due to a strike in the Spanish customs division most of the wheels, produced by Spanish company Braid Wheels, did not arrive in time. Due to not having enough wheels only three cars could start the first race.[5] The drivers (Van Dongen, Wagner, Hrobarek and Rosina) had their first racing experience with the Praga R1 on May 17. Danny van Dongen was the fastest Praga in free practice, setting a third time overall behind two Radical SR8's, and in front of a Norma M20F and two Radical SR3's.[6] Danny van Dongen took the first pole position in the PR1 class, fourth overall.[7] Stefan Rosina won the first race.
