The GTE-Pro class Aston Martin Vantage GTE has been given power and weight breaks ahead of next weekend’s FIA World Endurance Championship season-ending Six Hours of Bahrain.

The FIA confirmed Friday the final Balance of Performance adjustments of the year, which sees the Aston Martin get a 5kg reduction in minimum weight as well as a 0.2 mm larger air restrictor.

The remainder of the GTE-Pro competitors, meanwhile, will have minor weight increases, with the Porsche 911 RSR, Ford GT and Ferrari 488 GTE all getting 2kg added.

The changes come as part of the new-for-2017 automated BoP system.

While the GTE-Pro class Aston Martin has been given weight and power breaks, the team’s GTE-Am entry will face a 10kg weight increase and 0.2 mm smaller air restrictor in Bahrain.

Paul Dalla Lana, Pedro Lamy and Mathias Lauda head into the title-decider leading the GTE-Am points, ten points ahead of Dempsey Proton Racing’s Matteo Cairoli, Christian Ried and Marvin Dienst.
