Appendix J Touring Cars was an Australian motor racing category for modified, production based sedans.
[1] Under Appendix J, eligibility was restricted to closed cars with seating for four persons and at least one hundred examples of the model had to have been produced.
[2] Bodywork and interior trim had to remain virtually standard; however, engines and suspensions could be modified to improve performance and handling.
[5] In 1981 CAMS introduced the Group N Touring Cars category which was intended to recreate the style of racing which had existed under the Appendix J rules.
[3] Originally Group N was restricted to cars manufactured before January 1965; however, this was later extended to permit models produced up to the end of 1972.
