Porsche tuner Gemballa has announced a new kit for the Porsche 911 997 Turbo, called the GT 550.
The kit is specially designed for the 997 model and provides increased aerodynamics and a boost till 500 bhp. A run to 62 mph is made in 3.8 seconds and with an overboost in 3.6 seconds.
A front spoiler reduces lift on the front axle, while new side skirts maintain design consistency. The air inlets help to cool the tires and brakes. The large main spoiler creates a downforce for the rear axle.
