Ahead of next weekend’s Oak Tree Grand Prix at Virginia International Raceway, the GT Daytona Aston Martin and Dodge are the next cars to have Balance of Performance adjustments.
The Aston Martin V12 Vantage that is currently leading the championship with TRG-AMR will have a 1 mm air restrictor reduction and 250 less RPM.
The Dodge Viper SRT GT3-R that won last time out at Road America will have 3 mm taken off its air restrictor, a reduction of 200 RPM and a raise of 10kg in its minimum weight.
Furthermore, a larger fuelling restrictor is given to the Audi R8 LMS squads whilst the Ferrari 458 Italia has a slight reduction for the upcoming round.
No cars will have a fuel capacity alteration, despite both TRG-AMR and Riley Motorsports having complained pre-race about being unable to make the 60-minute minimum drive time on a single stint.
Instead, the minimum drive time was reduced to 50 minutes for Road America, and will remain as this for the Virginia International Raceway round.
The Oak Tree Grand Prix is the sole GT-only round of the season, and is open only to the GT Le Mans and GT Daytona categories.
