This mod includes 3 layouts imagining a fully refurbished Calder Park, a circuit opened in 1962 near Melbourne which has suffered financial struggles and competition with other in the countries and has been used recently mainly from drag and drifting events.
The Thunderdome Oval remains as the original, the ~2.5km National Circuit has been widened and modernized and it’s linked to the oval for a 4.2km mixed layout, which can be used by Indycar and F1, in a new experiment since Indianapolis.
