The C8.Rs had been hit twice with BoP and to just hit again the day before this weekend's race starts

The C8.R teams were already unhappy with the C8.Rs pace and qualified well down the GTD-Pro class with a P8 and P9 finish during last Sunday’s qualifying race.

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, (2,900 lbs) 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 piss poor 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.
