These recent spy photos show the 991 GT3 testing in Sweden. With very little camouflage we can see how the car is shaping up. We know it will have longer wheelbase (pushed out to each corner) and have a wider track up front compared to the rear. Larger brakes, more horsepower (rumored 500hp), and only one transmission (rumored PDK). A change on the exterior from all other GT3's is the fixed rear wing. This 991 version appears to change to a retractable spoiler, but Porsche may be saving that for the official debut.
