IMSA has made no significant changes to the Balance of Performance for the Rolex 24 at Daytona, including keeping the Porsche 911 GT3 R in the same specification that it ran in official pre-season testing.
Confirmed in the release of the Rolex 24 BoP tables on Tuesday, the debuting Type-992 Porsches will be unchanged heading into the start of practice for the WeatherTech SportsCar Championship season opener on Thursday.
It comes after all seven of the cars were at the bottom of the time sheets in combined Roar Before the Rolex 24 results prior to qualifying, where Jan Heylen posted the quickest time of a Porsche in 21st overall, 2.8 seconds slower than the GTD class pole-sitting No. 57 Winward Racing Mercedes-AMG GT3 Evo.
Mercedes-AMG, meanwhile, was on the opposite end of the spectrum with four of its cars placing in the top four in combined qualifying and also not receiving a change.
The only BoP adjustment across the GTP, and common GTD Pro and GTD BoP tables is a two-liter increase in fuel capacity for the BMW M4 GT3, moving from 97 to 99 liters.
No word has been given if the LMP2 class will receive any class-wide performance adjustments, amid concerns of the category’s stratification with LMP3 cars.
In a change for 2023, IMSA is not issuing BoP tables for the LMP2 class, which is made up exclusively of Oreca 07 Gibsons.
