Supercars has ratified a centre of gravity (CoG) change in a move to equalise the two Gen3 models with immediate effect.

CoG testing took place after the Beaurepaires Melbourne SuperSprint earlier this month.

Nine cars from a number of teams were tested at Tickford Racing’s Campbellfield headquarters.

A difference of 2.3mm was measured between the average of the Gen3 Ford Mustangs and Chevrolet Camaros.

In response to the difference, Supercars has ratified an adjustment to the Camaro.

An adjustment of 4.97kg will be made on the bar just behind the fuel cell of the Camaro.

The changes are in line with the adjustments seen on the Gen2 Ford Mustang in 2019.

"The Technical Working Group has recently conducted testing and measured a CoG (Center of Gravity) difference of 2.3mm between the average of the Gen3 Ford Mustangs and Chevrolet Camaros,” a Supercars spokesperson said.

"To address this difference, an adjustment of 4.97kg will be made on the bar just behind the fuel cell of the Chevrolet Camaro.

"This adjustment is in line with previous adjustments made in 2019, when 28kg was added to the roof of the Mustang.

"The adjustment to the Gen3 Camaro will be made in a lower and more rearward position, equal to 1.8kg if placed in the same position as in 2019."

It comes after changes to the Gen3 chassis were recently signed off by the Supercars Commission and Technical Working Group.

The Technical Working Group approved some modifications to the front and rear clips, and chassis, to improve the impacts of damage learnt from Albert Park.

The new changes will be in effect from next weekend's third round of the season in Perth.

Erebus Motorsport Camaro driver Brodie Kostecki leads the championship heading to his native Western Australia.

Kostecki leads Walkinshaw Andretti United Ford star Chaz Mostert by 32 points.

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