Now that IMSA has had the opportunity to review the data and crunch the numbers following the three-day “Roar” test earlier in January at Daytona International Speedway, the series’ competition committee has issued the Balance of Performance tables to the teams.
With the exception of the BMW M8 which had its fuel capacity increased by 2 liters to 90L, the rest of the GTLM class will keep the same set-up as they had when they went into the Roar test.
For Corvette Racing, it’s minimum weight is 1240kg which is the same as the Porsche 911 RSR GTE and lighter than the Ferrari 488 (1270kg) and the Ford GTs (1285kg). The BMW M8 comes in the lightest at 1220kg. The C7.R’s air restrictors are set for 30.6mm and it has a total fuel capacity of 91 liters.
Here’s the IMSA Technical Bulletin for the GT Le Mans class:
Race authorities also kept a hands-off approach to the DPi and LMP2 classes with just minor fuel adjustments but they did make some changes to weight and air restrictors for competitors in the GTD class.
The Rolex 24 at Daytona takes place on Saturday, January 26th.
