IMSA has given both the Chevrolet Corvette C8.R and BMW M4 GT3 additional weight ahead of this weekend’s Rolex 24 at Daytona.

Confirmed in a pre-event Balance of Performance table, the Corvette will now run at a minimum weight of 1335 kg, marking a 15 kg increase compared to its configuration in last weekend’s Roar Before the Rolex 24, with the BMW handed 10 kg of additional weight.

Both cars, however, have been handed aero adjustments that should help with straight-line speed, with the Corvette set to run at an 8-degree minimum rear wing angle (-3 degrees) and the new-for-2022 BMW at -2.2 degrees after previously being set at 0 degrees.

Additionally, the BMW will lose 4 liters of fuel capacity.

The changes come after both cars appeared to struggle for pace in the Roar, with the Corvettes finishing eighth and ninth and BMWs in 12th and 13th in the 13-class GTD Pro class prior to several post-race penalties for tire pressure infringements. 

Other changes to GTD machinery include a 25 kg weight break and 4-liter fuel capacity increase for the Acura NSX GT3 Evo22, a 1-degree increase in minimum rear wing angle to the Lamborghini Huracan GT3 Evo and 1.2-degree increase for the Mercedes-AMG GT3 Evo.

The McLaren 720S GT3, meanwhile, has been given a 4-liter increase in fuel capacity, with no power adjustments made to any GTD cars.

No BoP changes have been made to the DPi class, which remains unchanged since the start of the Roar.

IMSA WeatherTech SportsCar Championship cars will return to Daytona International Speedway beginning on Thursday with three practice sessions.
