It may be hard to recognize, but the GT3 sits more than an inch closer to the ground than a 911 Carrera, a design characteristic aimed at improving handling. Likewise, the exterior has been massaged in the quest of speed, with a revised front fascia and lower spoiler to increase down force, vents for radiator and brake cooling, and a rather large rear wing which provides even more down force, and, as a result, improves handling and stability at high speeds. Distinctive alloy wheels measure 19 inches, though the rear rims are roughly 50 percent wider than those up front.
