Balance of Performance updated ahead of 2026 Meguiar’s Bathurst 12 Hour

SRO Motorsports Group has updated the Balance of Performance regulations ahead of the Sunday's Meguiar’s Bathurst 12 Hour.

The 2026 edition of Australia’s International Enduro will commence at 5:45am local time.

Mercedes-AMG secured a 1-2-3 in Saturday’s Pirelli Pole Battle, with Scott Taylor Motorsport’s Cam Waters claiming his maiden Allan Simonsen Pole Trophy.

Ahead of Sunday’s race, a series of pre-race Balance of Performance changes have been locked in.

Five kilograms have been added to the 10 Mercedes-AMG entries, which will be run by STM, Craft-Bamboo, Tigani Motorsport, Heart of Racing by SPS, GWR/RAM, 75 Express, Grove Racing, and Team GMR.

The two Arise Racing-run Ferrari 296s have had 15 kilograms reduced, along with a rear wing angle reduction and turbo increase.

The Aston Martin Vantage (Volante Rosso), Chevrolet Corvette Z06 (JMR), and McLaren 720S (Optimum Motorsport, Volante Rosso) have all been given a 10 kilogram reduction.

The Corvette has also been given a minor reduction in minimum rear wing angle from 6.5 degrees to 6.2 degrees.

It comes after the two JMR Johor Racing Corvettes qualified 25th and 26th out of the 31-car GT3 field.

The Audi R8, BMW M4, Porsche 911, Ford Mustang and Lamborghini Huracan remain unchanged.

Sunday’s race will commence at 5:45am local time.
