The ACO has confirmed the latest round of Balance of Performance adjustments for European Le Mans Series competitors ahead of this weekend’s Four Hours of Paul Ricard.
The changes affect the Porsche and Aston Martin entries in LMGTE.
Both the 2012 and 2013-spec Porsche 997 GT3 RSR receives a 20kg reduction in minimum weight (1210 to 1190 kg), while the 2012-spec car sees the height of its gurney reduced by 10mm (25 to 15 mm).
The minimum weight of the latest specification Porsche 911 RSR, which makes its series debut this weekend, has been increased by 5 kg.
The 2012-spec Aston Martin Vantage, meanwhile, will now run at a minumum weight of 1160 kg, some 85 kg less than the base weight of the car, while the 2013 cars will run at 1165 kg.
Both cars will also have small restrictor increases, with the 2012-spec Aston now at 29.7 mm and the 2013 cars at 29.4 mm.
A change has also been made to the GTC category, which sees the 2013 and 2014-spec Porsche 911 GT3 R have a 4 mm larger air restrictor (56 mm to 60 mm).
