All but one car in the GTE-Pro and GTE-Am classes have received Balance of Performance adjustments ahead of this weekend's penultimate round of the FIA World Endurance Championship season in Shanghai.
Sweeping changes have been made in both production-based classes, largely in power and weight.
In GTE-Pro, the Porsche 911 RSR, Aston Martin Vantage GTE and Ferrari 488 GTE have all received power increases, with the Porsche getting a 0.4mm larger air restrictor and a 0.2mm increase for the Aston, following its 0.4mm reduction prior to the last round at Fuji Speedway.

Three of the four GTE-Am cars, meanwhile, have been given weight adjustments. The Porsche 911 RSR loses 10kg, while the Aston has been given a 10kg increase and the Corvette C7.R getting a 5kg weight break.
No change has been made to the GTE-Am championship-leading Ferrari F458 Italia.
It marks the ninth BoP change to the GTE category in eight races this season.
