The Chevrolet Corvette Z06 GT3.R and Lamborghini Huracan GT3 EVO2 have been given the largest weight breaks ahead of next weekend’s Chevrolet Grand Prix at Canadian Tire Motorsport Park.

As reflected in the latest version of the Balance of Performance, issued by IMSA on Thursday, the Corvette drops 12 kg from its most recent configuration in last month’s Sahlen’s Six Hours of The Glen.

It is countered, however, by a 1.7 percent and 1.2 percent reductions in power at the first and second stages, respectively.

The Huracan GT3 EVO2, meanwhile, loses 13 kgs, and faces a 2.6 percent power reduction at speeds under 190 km/h but a marginal 0.3 percent increase at 200 km/h and higher.

The BMW M4 GT3 EVO and Lamborghini Temerario GT3 are the only other cars to receive weight breaks for the Mosport round, with the BMW losing 5 kgs, and having a +0.9 percent and -0.5 percent change at power levels, respectively.

The new-for-2026 Lamborghini Temerario GT3, meanwhile, gets a 3 kg weight break but considerable 8.2 percent increase in Stage 1 power levels but a minor 0.3 percent bump in Stage 2.

Of note, the maximum rear wing angle has been adjusted from 5.2 to 6.8 degrees for the car.

The Aston Martin Vantage GT3 Evo, which scored a podium finish in GTD last time out, faces a hefty 20 kg increase in minimum weight, although the car will benefit from increased Stage 1 (+2.2 percent) and Stage 2 (+2.9 percent) levels.

Porsche’s 911 GT3 R Evo, meanwhile, gets a 7 kg weight increase but 2.9 percent power bump at the first stage, which will see the car run at 100 percent maximum declared power at both stages, the only GT3 model to do so.

Minor power tweaks have been made to both the Ferrari 296 GT3 Evo and Ford Mustang GT3 EVO, with no weight changes to either car, with the Lexus RC F GT3, also remaining at the same weight, losing 0.1 and 2.8 percent in the power stages, respectively.

The same is the case for the Mercedes-AMG GT3 Evo (-1.4 percent/+1.6 percent) and the McLaren 720S GT3 Evo (-0.7 percent/+1.8 percent).
