{{Main|Dunlop Super2 Series}}
A second-tier series, the Dunlop Super2 Series, is run as a support category to the main series at certain events.<ref name="V8 About" /> Initially for privateers who did not have the funding of the professional teams in the late 1990s, the series now serves the dual purpose of developing young drivers before they compete in the main series and a means for main series teams to give their endurance co-drivers more racing experience prior to the endurance races. Teams in the Dunlop Super2 Series compete with cars previously used in the main series. From the 2021 Season until the end of the 2024 season the Dunlop Super2 Series would compete as a class alongside the Super3 Series V8 Supercars class racing together on track at the same time. In the year 2025 season the Super3 Series would be axed due to low grid numbers in the 2024 season reverting back to a single class of the Dunlop Series.

A third V8 Supercar-based series, the [[V8 Touring Car National Series|Kumho Tyres V8 Touring Car Series]], had been run since 2008 until the end of 2024, but had no involvement with the Supercars Championship or Dunlop Super2 Series, instead running on the programme of the [[Shannons Nationals Motor Racing Championships]].<ref>{{cite web | url=http://thenationals.com.au/index.php?page=kumho-tyres-v8-touring-cars | title=Kumho Tyres V8 Touring Cars | publisher=Shannons National Motor Racing Championships | access-date=1 July 2013 | archive-date=18 July 2013 | archive-url=https://web.archive.org/web/20130718201848/http://thenationals.com.au/index.php?page=kumho-tyres-v8-touring-cars | url-status=dead }}</ref> However, since 2016, several rounds have been run as support categories at Supercars events. It would officially become the third-tier series of V8 Supercars starting in 2019 before the category known as the Super3 Series would join as a class alongside Super2 Series Class V8 Supercars starting in the 2021 season. In the 2023 Season the V8 Touring Car Series would be revived to create an unofficial standalone fourth-tier level V8 Supercars category using V8 Supercars sold to teams that are no longer racing in the Super3 Series of the Dunlop Super2 & Super3 Series, however it would only last for that year's season. The Super3 Series would officially be axed in 2025 and become defunct due to low grid numbers with only as many as two or three cars appearing at rounds in the 2024 Dunlop Super2 & Super3 Series season.
