IMSA has handed out Balance of Performance adjustments to a pair of GT machines ahead of this weekend’s race at Circuit of The Americas.
After destroying its Porsche in Baltimore, Team Falken Tire will roll out with a 2010-spec 911 GT3 RSR, which has been given a number of concessions, as outlined in a technical bulletin released late last week by the series.
Compared to the 2013-spec wide-body model, Falken’s Porsche will be allowed to run 10 kgs lighter, as well as with a 0.2 mm larger air restrictor. It will also be permitted to use the 2013 rear wing and front spoiler, per IMSA’s bulletin.
The other BoP change comes with the Ferrari F458 Italia, which has received a 0.6 mm larger air restrictor, the same size that Extreme Speed Motorsports was allowed to run last year.
Risi Competizione, one of two Prancing Horses in the ALMS field, will also be looking to bounce back after a dreaded Baltimore.
The two-hour and 45-minute ALMS race, part of the double-header weekend with the FIA World Endurance Championship, is set for Saturday afternoon.
