These meetings were held as part of the Shannons Nationals Motor Racing Championships,[1] at Sandown Raceway on 21 and 22 September and The Bend Motorsport Park on 16 and 17 November.
As the championship is a spec series, all competitors raced with an identical Onroak-Ligier chassis powered by a naturally-aspirated 5.0-litre Ford Coyote V8 engine.
[21] However, after the organisers announced that the series would be delayed four months due to supply issues as well as further S5000 car testing, the first race of the series was pushed back to 22 September, 2019 at Sandown Raceway.
Drivers in the top 75% of the field then selected their grid position for the first qualifying heat (held on Saturday), with the top ten positions reversed for the second qualifying heat, held on Sunday.
[24] The grid for the Main Event was defined by the points earned by the drivers across the weekend, held later on Sunday.
