Touring Car Masters is an Australian motor racing series open to modified touring cars manufactured between 1 January 1963 and 31 December 1980.

[1] 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.

[2] These improvements would have been against the spirit of Group N regulations which are focused on vehicles racing as much as possible as they did in the period when the cars were new.

Each model is allocated into one of three classes by the appointed category managers, TCM Racing Pty.

[1] Performance parity is maintained between disparate models by varying maximum engine revolutions and minimum racing weights of those vehicles.
