Supercars have confirmed a fresh round of aerodynamic adjustments to the Chevrolet Camaro for the Tasmania Super440 at Symmons Plains, with motorsport boss Tim Edwards telling teams the work is the second step in a process designed to shrink the championship's Balance Parity window between the Camaro and the Ford Mustang.
Three specific changes will be implemented for the Tasmania round. The Camaro's front splitter will be moved forward to its original pre-Christchurch position; a small packer will be installed along the front facia wheel band; and the rear wing angle will be increased by 0.4 of a degree. The package is, in effect, a partial reversal of the changes made for the Christchurch round at Ruapuna, where the splitter leading edge was reduced, the rear wing was moved rearward and upward, and the wing angle was reduced.
The trigger for the rethink came from inside the Camaro camp. General Motors and Triple Eight homologation partner Team 18 were openly dissatisfied with the post-Christchurch result, believing the package had not delivered the aerodynamic balance shift Supercars and the manufacturer were aiming for. Their data analysis has been the foundation of the case put back to Supercars in the past fortnight.
In a written communication to the Supercars Commission, Edwards described the move in measured terms. "Post the change that was made to the Chevrolet Camaro at Christchurch, Supercars have undertaken further" technical analysis to optimise performance, he said. He confirmed that "consultation has taken place with the three homologation teams and the change will be implemented for the Tasmania round."
Edwards also signposted the broader strategy. He said Supercars would "continue to investigate small adjustments to the Camaro that would allow us to significantly reduce the size of the Balance Parity box" - a reference to the in-season ride-height and downforce adjustment ranges that have been expanded since the Gen3 era began, but which homologation teams now want pulled back so weekend-to-weekend setup work is not undone by category-led parity tweaks.
For the Camaro teams, the immediate question is whether the package can deliver a meaningful pace step on a circuit as low-grip and tyre-aggressive as Symmons Plains. The previous round in Christchurch saw mixed results for the Chevrolet runners, with Will Brown losing the championship lead and the post-race conversation dominated by chassis damage and parity grumbles rather than racing.
Team 18 used a Queensland Raceway aerodynamic test in early May to evaluate the Camaro across the back end of the proposed change package, with data shared back to Supercars and General Motors. The Tasmania version is the result of that work, with Edwards making clear that further adjustments could follow at Townsville and Sandown if the field still does not converge.
The Mustang teams - including Tickford, Dick Johnson Racing and the Ford Performance squad behind Anton De Pasquale - have so far stayed largely silent in public on the latest changes, but are understood to be content with the framing that Tasmania is part of a process rather than a one-off concession to General Motors.
The Tasmania Super440 runs from Friday with practice and qualifying ahead of three races on Saturday and Sunday, with each Sunday race extended in length compared with previous Symmons Plains weekends. Brad Jones Racing's Anton De Pasquale heads the field on countback going in, with the Camaro response to the new package expected to set the tone for the rest of the championship's middle stretch.
