The February 21 test won’t be run by Supercars itself, rather operating as a ‘team’s test’ which means it will come out of each entry’s bank of three allocated test days for the year.

Each of the teams will be allocated four sets of what is now known as the soft tyre (marked with yellow signage) and four sets of the new-spec super soft (marked with white signage).

The test won’t be strictly compulsory for the Supercars teams, and it also won’t be open to the public.

“With the introduction of a new tyre, the Team Representatives on the Supercars Commission decided that a pre-season test at a neutral venue was necessary so that all teams and drivers could experience the characteristics of the new tyre before racing on them,” said Supercars Australia Sporting and Technical Director David Stuart in a statement published on the official Supercars website.

“Whilst the day is not compulsory, it will be in the best interests of teams to attend as this change will represent a significant new technical challenge. Ensuring that teams have sampled the tyres and been able to collect data to analyse before the beginning of the racing season will be vital to on-track performance.

“The results of the laboratory testing that we are currently conducting will be supplied to all teams ahead of this test so that they can work through their chassis set-up changes needed to make the most of the construction change.

“The choice of Sydney Motorsport Park means that all teams will have the same testing opportunity, with every team at the neutral venue on the same day providing equality whatever the weather and track conditions.

“What this new construction should provide is a different kind of feedback for drivers and engineers, and track time is the only way to effectively analyse this new feedback.”

Intimate details of Dunlop’s new direction with the Supercars compounds were first published by Motorsport.com back in October.
