Aerodynamics and design
The TÜV-certified Aerokit I is the successful outcome of intensive development work in the wind tunnel. At the same time, the PUR-RIM components fitted increase the downforce on the axles and also improve the driving stability. The front spoiler I underscores the dynamism of the 911 Carrera 4S and, by optimizing the air flow, helps to ensure effective cooling of the braking system. At the same time, side skirts emphasize the powerful contours. Depending on requirements, a roof spoiler and three versions of rear wings permit precision aerodynamic tuning on the rear axle. By way of example, back pressure air vents have been integrated into the variable rear wing IV along with an additionally adjustable spoiler lip (gurney flap). The dynamic character is also emphasized by decorative trims for the exterior mirrors – made from carbon fiber painted in the requested color, decorative headlamp surrounds, a low swung rear diffuser plus the new sports exhaust systems.

New TECHART flap-controlled exhaust system
For the Porsche, TECHART has developed two versions of a new exhaust system. The “Sport” version, for instance, features two rear mufflers with an exhaust flap, an exhaust flap control unit in addition to double-oval tailpipes in a polished or black chromium finish. The “Racing” version is also equipped with two stainless steel high-performance headers and a sports catalyst. Drivers can choose between either a production-vehicle-like sporty sound or a powerful racing car sound. The “Racing” version also helps to boost the performance significantly by 35 bhp in the upper speed range.

TECHART suspension
Firm sporty handling is ensured by TECHART’s VARIO coilover suspension in addition to a set of TECHART sports springs. The VARIO PLUS version is available for vehicles with PASM. Both systems feature coilover shock absorbers with an adjustable rebound and pressure stage plus special main and additional springs. TECHART Formula and Formula II alloy wheels, available as a five-spoke wheel in either a single-piece or composite design, underscore this sportiness. For the new 911 models, a light alloy forged wheel - the TECHART Formula III forged - is available in a twin-spoke design in a 19 and 20 inch format. By way of an option, the TECHART nose lift system is also available for negotiating curbsides and other ramps. At the touch of a button, it is possible to raise the automobile by up to 60 mm – even when driving at up to 60 km/h.

Individual in every detail - the interior
A plethora of different leather interiors, color-coordinated three-spoke airbag sports steering wheels, aluminum pedals and trim strips are just a few of the interior options available. Thanks to the TECHART craftsmanship, virtually no bounds are set when it comes to realizing a customized design.
