Chris Hodgetts won the title with his class C Toyota Corolla.
All races were held in the United Kingdom.
Points were awarded on a 9, 6, 4, 3, 2, 1 basis to the top six finishers in each class, with one bonus point for the fastest lap in each class.
Unlike previous seasons, full points were awarded to all classes regardless of how many cars started.
Only a driver's best seven scores counted towards the championship.
