Sebring BoP Sets Baseline for 2019

-

The second IMSA WeatherTech SportsCar Championship race of 2019 will set initial Balance of Performance benchmarks for the remainder of the season due to the season-opening Rolex 24 at Daytona’s treatment as a one-off event.

The changes reflected in IMSA’s BoP tables for the upcoming Mobil 1 Twelve Hours of Sebring span all four classes and are adjustments made based on how the cars ended the 2018 season at Petit Le Mans.

Compared to Daytona, all DPi cars except the Nissan Onroak DPi will head to Sebring with added weight. Boost levels for the turbocharged Acura ARX-05, Mazda RT24-P and Nissan DPi are down while the naturally aspirated Cadillac DPi-V.R — saddled with the largest weight increase — has no change to its air restrictor. Fuel capacities remain unchanged except for a 2-liter reduction for the pair of Mazdas.

In the two-car LMP2 class, the ORECA 07 — the only global-spec car currently competing this year — is identical to its Daytona except for a slight reduction in the minimum angle of its rear wing flap.

Modifications to GT Le Mans BoP benefit the Ford GT and Ferrari 488 GTE with both cars losing weight and gaining fuel capacity and boost pressure. The Corvette C7.R features larger air restrictors and greater fuel capacity while the BMW M8 GTE loses weight and boost pressure. The only change for the Porsche 911 RSR compared to Daytona is a 15 kg weight increase.

Four updated cars in the GT Daytona class have led to many changes compared to last season. Relative to the Rolex 24 at Daytona, each of the eight GT3-spec models will compete at Sebring with a different minimum weight and all but the BMW M6 GT3 have adjusted fuel capacities. Boost levels are down for the Acura NSX GT3 and up for the Ferrari 488 GT3.

The 12-hour contest will conclude 36 hours of endurance racing in the state of Florida March 16 at Sebring International Raceway.
