The 2025 National Sports Sedan Series, known as the Precision National Sports Sedan Series after its title sponsor, was a motor racing series for Australian Sports Sedans. The series has very liberal regulations allowing a broad range of custom-built racing cars to participate, with the proviso that they have bodywork resembling a road car. A national competition for sports sedans dates to 1976, and the present series to 2004.
The series was sanctioned by Motorsport Australia, and its naming rights sponsor is Precision International, a supplier of specialty parts for racing engines.
The series was won by Steven Tomasi driving a Holden Calibra.Garry O'Brien, 24 November 2025, Sports Sedan round and title win for Tamasi, speedcafe.com, as archived at web.archive.org
