I searched informations about Spanish and Thailand series.
Spanish series will run alongside the Campeonato de España de Resistencia in the "Clase 1", with five events: Catalunya, Lédenon, Aragón, Valencia and Jarama.
Thailand series will run a stand-alone series within the Thailand Super Series weekends. Three races in Buriram (the last one with the Asia series), then the 28 August round of the International series (not clear because it will be ran in Shanghai, not in Thailand), a round in Bira Circuit and the final in Bangsaen Street Circuit.
