Supercars explains Gen3 chassis updates, CoG testing

Supercars has detailed changes to the Gen3 chassis, as well as an update to recent centre of gravity (CoG) testing.

A number of cars were subject to CoG testing after the Beaurepaires Melbourne SuperSprint.

Cars from both marques underwent CoG measurements on a special rig at Tickford Racing's Campbellfield base.

According to a Supercars spokesperson, preliminary results between the Ford Mustang and Chevrolet Camaro are “very close”.

“Work continues, preliminary results show the two cars are very close,” a Supercars spokesperson said.

“A more in depth analysis and study involving different car configurations is underway.”

Changes to the Gen3 chassis have also been signed off by the Supercars Commission and Technical Working Group.

A number of cars suffered accidents at the Albert Park round, and some were sidelined from sessions due to repairs.

Notably, Tim Slade was forced out of the Race 3 and 4 qualifying sessions after crashing in Practice 1 in Melbourne.

Shane van Gisbergen also missed Practice 2 after crashing shortly after Slade found the Turn 5 wall.

Both cars sustained damage to clips, as did the cars of Macauley Jones, Mark Winterbottom and Jack Le Brocq, who all crashed in Race 5.

Supercars maintained that the changes are in line to the “continuous improvement” exercises adopted when the last new platform — Car of the Future — was introduced.

“The Technical Working Group approved some modifications to the front and rear clips, and chassis, to improve the impacts of damage learnt from the Albert Park findings,” a Supercars spokesperson said.

“This is a process of continuous improvement similar to what the series went through the last time it introduced a new platform.”

The 2023 Repco Supercars Championship will resume at the Bosch Power Tools Perth SuperSprint on April 28-30.
