The Aston Martin Vantage GT3 has received its second consecutive Balance of Performance adjustment ahead of next weekend’s Acura Sports Car Challenge at Mid-Ohio.
It is one of several BoP changes confirmed by IMSA on Monday prior to the Sept. 25-27 race.
The new-gen Aston, in its first season of IMSA WeatherTech SportsCar Championship competition, has been given a 30 kg weight break, bringing the car’s minimum weight down to 1270 kg.
It comes one race after receiving an increase in turbo boost in the range of 9.5 horsepower prior to the six-hour enduro at Michelin Raceway Road Atlanta, where The Heart of Racing scored a season-best sixth place class finish.
No other performance-related changes have been declared for Mid-Ohio, other than fuel capacity adjustments for the Acura NSX GT3 Evo (-1 liter), Lexus RC F GT3 (+2 liters) and Porsche 911 GT3 R (+1 liter).
The BoP for the GT Le Mans class remains unchanged while both the Mazda RT24-P and Cadillac DPi-V.R have been given 3-liter increases in fuel capacities.
Monday’s BoP declaration, ten days prior to the start of on-track activity, is the earliest seen this year as part of a more streamlined and transparent effort undertaken by IMSA’s technical department.
