Ford and BMW are among the manufacturers that have received Balance of Performance adjustments ahead of next weekend’s Michelin GT Challenge at Virginia International Raceway.

Issued on Thursday by IMSA, the pair of Chip Ganassi Racing Ford GTs have been handed a 5 kg increase in minimum weight, although will benefit from a roughly 10 horsepower increase for the second and final GT-only round of the IMSA WeatherTech SportsCar Championship season.

Ford, which is coming off back-to-back GT Le Mans class wins, will also have a 2-liter larger fuel capacity.

BMW’s M8 GTE, meanwhile, will face a 6.5 horsepower reduction in the mid-to-high RPM range, along with a 1-liter reduction in fuel capacity.

No changes have been made to any other GTLM cars, including the points-leading Porsche 911 RSRs.

Audi, Ferrari Get Weight Breaks in GTD

The Audi R8 LMS GT3 Evo and Ferrari 488 GT3 have been given reduced minimum weights in GT Daytona, meanwhile.

A 20 kg reduction is on tap for the Audi, with the Prancing Horse set to benefit from a further 10 kg weight break after a previous reduction earlier this summer.

The only other adjustment in GTD comes with the McLaren 720S GT3, which gets a 4-liter reduction in fuel capacity.
