Supercars announces pre-Perth parity tweak

SUPERCARS has announced its first in-season parity change of 2023, with weight to be moved higher on the Chevrolet Camaros.

The decision follows Centre of Gravity testing conducted at Tickford Racing’s headquarters on April 3-4, immediately after the Melbourne SuperSprint.

Results came to light earlier this week regarding the closeness of the testing, although there have been subsequent suggestions that only a portion of the data was released.

Either way, a tweak has now been ordered.

“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,” said a Supercars spokesperson.

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

Supercars noted the magnitude of the change is far smaller than seen four years ago when the parity saga last peaked.

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

“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’s not yet clear whether Ford engine parity concerns will lead to further changes.

Round 3 of the Repco Supercars Championship will take place at Wanneroo Raceway on April 28-30.
