Ever since Mansory acquired the former Porsche performance division of Swiss design firm Rinspeed, the Bavarian tuner has been releasing a slew of new models based around Porsche’s various models. Last week’s Geneva Motor Show saw several of the beasts unveiled, including the out-of-this-world Cayenne Chopster, but the list of cars just keeps on growing.

Today we have details about a new package based on the 997 Porsche 911. The program mainly focuses on improvements concerning the aerodynamics, engine performance and handling of this sports car icon, but as with any Mansory product the cars can be designed to meet a customer’s every whim.

When developing the 911 program, Mansory engineers attached great importance to an individual design but also aerodynamic efficiency. The core part of the bodykit is a lift-reducing front bumper. In connection with the hood, this bumper offers various design possibilities. A matching rear bumper is also available, and accommodates a new quad-pipe exhaust system.

Performance modifications have been kept to a minimum, consisting of only a sports air filter and high-flow exhaust system. Interestingly, this exhaust system has an electronically-controlled valve system that allows drivers to modify sound levels should the need arise – we’re thinking when the boys in blue pull up. Round out the list of modifications are a 30mm suspension lowering kit and 20in wheels shod with Michelin Pilot Sport tires.

Inside, customers can select a fully custom leather package, as well as aluminum and carbon-fiber trim.
