Supercars technical staff are in a race against time to deliver the results and suggested aerodynamic changes following a second Vehicle Control Aerodynamic Testing [VCAT] process carried out this week.
The VCAT process was carried out with homologation teams Triple Eight and DJR Team Penske from Monday to Wednesday at Oakey Army Aviation Centre.

With the annual pre-season test at The Bend Motorsport Park under five weeks away, the results from this week’s three days of aero homologation testing will prove crucial ahead of the season-opening Superloop Adelaide 500 across February 20-23.
Critically, Supercars head of motorsport Adrian Burgess said the results from the VCAT will be distributed across all teams so as to help encourage a more level playing field.
Burgess admitted calling for a second VCAT was “obviously regrettable” but stressed finding and rectifying errors was “equally still part of the process”.
“It’s a drastic step forward compared to what we have done in the part. You do find flaws, you do find errors,” Burgess said in a Supercars video.
“By our standards, it’s the most comprehensive VCAT we’ve done, hopefully it delivers the results.”

The second VCAT saw teams arrive at 4am and leave around 10pm in order to get the most out of ideal weather conditions.
Rigorous testing saw several different ride heights and setups used to enhance the likelihood of expected results.
Burgess conceded “a lot more downforce off the cars if we wanted to” but it would have encouraged additional costs for teams in the guise of front bar and rear wing changes, as well as other external changes.
Regardless, Burgess was keen to avoid mid-season changes like those which plagued the 2019 season with a tense parity debate following the raging success of the new-for-2019 Ford Mustang Supercar.
“What we’re trying to work is something quick and easy that the teams can introduce from the end of this VCAT once we scanned the cars and reprocessed the data, we’ll be able to have these changes in place for the test at Tailem Bend,” said Burgess.
“It’s definitely the direction we need to go … we’re all happy with it and I believe the pit lane is happy with the processes we’re putting in place.
“Yes, it is more complicated, it takes more time to achieve the result we want, but ultimately it’s about trying to achieve parity and equitable racing and that’s clearly what we want to see.
“Last year was hard for everybody making the changes, so we’ve taken the necessary steps to try to eradicate that issue from last year.”
