Porsche, Aston Martin and Corvette have all been given Balance of Performance adjustments ahead of next weekend’s FIA WEC Six Hours of Fuji.
Following back-to-back class wins, the GTE-Pro class Porsche 911 RSRs have been given a 5 kg weight increase, cutting its initial post-Le Mans 10 kg weight break in half.
Both GTE-Pro and GTE-Am class Aston Martin Vantage V8s, meanwhile, will benefit from a 0.2 mm larger air restrictor, following an initial 0.5 mm reduction made prior to the Nurburgring.
The GTE-Am class Corvette C7.R has also undergone a change, but this time given a 20 kg weight break, as Larbre Competition searches for its first class podium finish of the season in Japan.
The Six Hours of Fuji is set for Oct. 9-11.
