Weight and power adjustments have been made to every car in the GTE-Pro class ahead of September’s Six Hours of Mexico, in the second round of changes to have come from the FIA’s new automated Balance of Performance system.

The Porsche 911 RSR, Ford GT and Aston Martin Vantage GTE have all been given 2kg weight breaks and slight increases in power, in the form of 0.1mm larger air restrictors for the normally aspirated Porsche and Astons and an equivalent increase in boost pressures for the turbocharged Ford.

Ferrari’s 488 GTE, meanwhile, has been given a 5kg weight increase and a decrease in boost across all rpm levels.

The changes have been automatically applied based on data from the last two regular-length WEC races at the Nürburgring and Spa, following the initial auto BoP application for the German round, which took into account the first two rounds of the championship.

While not under the new-for-2017 auto-BoP system, the GTE-Am class has seen a single adjustment made for Mexico, with the Ferrari gaining 15kg in minimum weight.

It brings the turbocharged Prancing Horse up to a minimum weight of 1303kg, some 70kg heavier than the next-heaviest car in the class, which is the Ferrari F458 Italia GT.

The Six Hours of Mexico is set for Sept. 1-3.
