A new field-wide Engine Control Unit (ECU) and bans on twin-spring dampers will shake-up the action under the bonnet at the Superloop Adelaide 500.
Supercars' technical update will see the new control ECU deployed by every team for the 2019 season, starting in Adelaide on February 28.
The new ECU was used at the all-in test day at Phillip Island last week.
Most teams appeared to run well with the new system, which has been developed by Supercars' technical team with supplier Motec.
Teams also began using new single linear front and rear springs as part of technical changes in the off-season.
Reigning champion Scott McLaughlin described the move to linears as probably a bigger change than the introduction of the Mustang bodyshell.
That move will force drivers to handle the car more than previously, with better balance in the front of the car set to negatively impact the rear, and nice-versa
"The linear spring was a big thing, trying to get used to how to drive it...," McLaughlin said at the test day.
"I've got to give something away. With the twin-spring you could rescue it in other parts of the corner, but now if you've got really good front you've got really shit rear.
"You've got to 50-50 it up a bit. Or be prepared to have something [sacrificed]."
The Superloop Adelaide 500 is the first event of the Supercars Championship and takes place from 28 February - 3 March 2019 at the Adelaide Street Circuit. Tickets are available here.
