Organised by the Classic Touring Car Racing Club (CTCRC), the championship is open to eligible four-seater saloon cars based on production shells marketed before 1 January 2011. Its broad regulations create an incredibly diverse field, bringing together cars from different generations and manufacturers that might rarely share a grid elsewhere.
Classic Thunder grids can feature everything from BMW M3s and Honda Civic Type Rs to Nissan Skylines, Holden Commodores and powerful V8 machinery, with multiple classes ensuring there is competition to follow throughout the field.
