Both the Mazda RT24-P and Nissan Onroak DPi will head into next weekend’s IMSA WeatherTech SportsCar Championship round at Long Beach with power increases, in the latest round of Balance of Performance adjustments.

The Nissan has been given an increase in turbo boost pressures across all RPM ranges, while the Mazda will benefit from a boost from the 2000-7000 RPM range.

The Rolex 24 at Daytona and Twelve Hours of Sebring-winning Cadillac DPi-V.R, meanwhile, faces a revised gear ratio, 2 liter fuel capacity reduction and refueling restrictor adjustment for the third round of the season.

No performance-related changes have been made to the Gibson-powered LMP2s, which serve as the baseline of the class, other than the Riley Mk. 30 getting a 2mm reduction in refueling restrictor.

BoP changes have also been made in the production-based ranks, with boost increases for both the BMW M6 GTLM and Ferrari F88 GTE in GT Le Mans, along with larger fuel capacities (3 liters for BMW, 1 liter for Ferrari).

The biggest change, however, comes with the Porsche 911 RSR, which has been given a 0.3mm reduction in its air restrictor, a 10kg weight increase and a 2-liter fuel capacity reduction.

Fuel capacities in GT Daytona, meanwhile, have been adjusted for all cars except the Acura NSX GT3 and Aston Martin V12 Vantage GT3.

Both the Lexus RC F GT3 and Sebring class-winning Mercedes-AMG GT3 have been given a 1.0 mm reduction in air restrictors, with the Acura getting a boost increase in mid-to-top end range.

The Mercedes-AMG gas also been given a 10kg weight increase, with the Porsche 911 GT3 R getting a 20kg weight break.
