IMSA has set the starting Balance of Performance for the remainder of the WeatherTech SportsCar Championship season.

Released on Wednesday, the BoP differs from January’s season-opening Rolex 24 at Daytona, which is a standalone table to the other WeatherTech Championship circuits due to the track’s unique oval/infield road course.

The BoP in the DPi class is unchanged when compared to the configuration raced in last year’s season-ending Mobil 1 Twelve Hours of Sebring, both in terms of minimum weight and power output.

While set to be an all-ORECA show at Sebring, BoP for LMP2 has also been detailed along with the GT Le Mans and GT Daytona classes.

The Porsche 911 RSR-19 has been given a 0.7 mm increase in its air restrictor (31.5 to 32.2 mm x2) compared to its end-of-year configuration while the BMW M8 GTE gets a turbo boost reduction across most RPM levels.

No change has been given to the class championship-winning Chevrolet Corvette C8.R.

GTD sees weight adjustments for the Acura NSX GT3 Evo (+10 kg) and BMW M6 GT3, Lexus RC F GT3 and Mercedes-AMG GT3 Evo (all +20 kg) although the Acura and BMW has been handed a slight increase in turbo boost levels.

The Lexus, meanwhile, will have a 1 mm larger air restrictor compared to its configuration from last year’a season finale.
