IMSA has set the Balance of Performance for teams running next week’s official test at Sebring, which sees a number of cars move from a Daytona-specific BoP to its standard configuration for the remainder of the WeatherTech SportsCar Championship season.

In Prototype, the Corvette DP gets a 0.3 mm larger air restrictor and 10 kg weight break, with the DeltaWing having a 10 kg weight increase and a reduction in boost across all levels.

While no weight or restrictor changes have been made to the Ligier JS P2 Honda, the Rolex 24-winning car sees a reduction top-level boost.

The Mazda Prototype, which shined in the early stages at Daytona, gets a 10 kg weight break and no adjustment to boost.

The Oreca 05 Nissan, which makes its WeatherTech Championship debut in Sebring with DragonSpeed, has yet receive weight, restrictor, fuel capacity or refueling restrictor specifications.

All P2 cars return to the standard high-downforce aero configuration after using the Le Mans-spec low downforce kits at Daytona.

Changes, meanwhile, have been made nearly across the board in the GT ranks, with both the Corvette C7.R and Ford GT in GT Le Mans getting 10 kg of additional weight, while the Porsche 911 RSR sheds 10 kg.

Additionally, the Corvette gets a 0.4 smaller air restrictor, with boost changes made to Ford (decrease) as well as the BMW M6 GTLM (increase).

In GT Daytona, the Dodge Viper GT3-R gets a 15 kg weight increase, with both the Porsche 911 GT3 R and previous-generation Audi R8 LMS ultra increased by 10 kg. The Ferrari 458 Italia GT3, meanwhile, gets a 10 kg weight reduction.

The Viper, consequently, gets a 1.0 mm larger air restrictor, with the Aston Martin V12 Vantage GT3 facing a 0.5 mm air restrictor reduction.

The BMW M6 GT3 has adjusted boost ratios (increase), while only the boost ratios for the new turbocharged Ferrari 488 GT3 have been confirmed for its configuration.

Also yet to be determined is the configuration of the Lamborghini Huracan GT3, with IMSA still evaluating the engines it impounded following last month’s Rolex 24.

IMSA has stated the adjustments have been made based on manufacturer-submitted data and its own data analysis.

Further changes are to be expected following next week’s two-day test and prior to the Twelve Hours of Sebring in March.
