The Mercedes-AMG GT3 Evo has been dealt a Balance of Performance hit for the Liqui-Moly Bathurst 12 Hour in an adjustment made between qualifying and the race.

A bulletin issued by SRO Motorsports Group on Saturday evening confirms a 10 kg weight increase for the Mercedes-AMG, which locked out the front row of the grid for Sunday’s endurance contest at Mount Panorama Circuit courtesy of drivers Maro Engel and Broc Feeney.

The Audi R8 LMS GT3 Evo II and the BMW M4 GT3 have been handed a 10 kg weight break, while the pair of Porsche 911 GT3 Rs in the field are now 5 kg heavier.

There is also a 10 kg reduction for the sole Lamborghini Huracan GT3 Evo entered.

SRO has additionally applied the turbocharged BMW M4 GT3s run by BMW M Team WRT with a small increase in turbo boost pressure at 5000-7000 revs per minute.

All of the other GT3 cars retain the same engine restrictor sizes that they were given at the start of the event, which opens SRO’s Intercontinental GT Challenge powered by Pirelli season.

Further down in the BoP bulletin, SRO has confirmed that the minimum starting tire pressure of 1.4 bar has been replaced with a ‘minimum hot pressure’ of 1.85 bar for each Pirelli tire after eight continuous green flag racing laps in a stint.

A post-qualifying BoP change was also carried out at last year’s Bathurst 12H when the Audis gained 15 kgs for race day after qualifying first and second.

The Liqui-Moly Bathurst 12 Hour starts at 5:45 a.m. local (Saturday, 1:45 p.m. ET).
