The Touring Car Masters is an Australian motor racing series open to modified touring cars manufactured between 1 January 1963 and 31 December 1978. It evolved out of a previous series for CAMS Group N Touring Cars but with a greater degree of modifications permitted to improve safety, reliability and affordability. These improvements would have been against the Group N regulations which are focused on vehicles racing as much as possible as they did in the period when the cars were new.
