When it comes to customizing their Porsche  sports cars by adding body kits and powertrain upgrades, customers have several tuning shops to turn to. On the flipside, there’s Porsche’s very own Exclusive division, which offers a range of subdued transformations that mostly include bespoke colors, various body trims, exclusive wheels, smoked tailights, and slightly improved interiors. This has been business as usual for Porsche Exclusive for quite a few years, but Stuttgart’s bespoke department also developed various aerodynamic kits for the 911. For 2015, the brand introduced the Aerokit Turbo for the forced-fed versions of the 991-generation 911.

As the name suggests, the Aerokit focuses on improving aerodynamics and increasing downforce, but it also helps the 911to stand out in a crowd. Keep reading to find out what sets this package apart from other Porsche Exclusive  offerings.

The Aerokit Turbo package consists of two key components: a front spoiler lip and a redesigned rear lid. Design-wise, the front spoiler lip is similar to those seen on competition 911s such as the GT3 Cup cars or the GT3 America. However, unlike these motorsport-spec GT3s, Porsche Exclusive’s splitter also comes with side fins for a more purposeful appearance. For the rear, the bespoke division prepared a more intricate update, consisting of a fixed trailing edge with side winglets and an automatically adjustable, retractable wing.

Customers can purchase the Aerokit in either the car’s body color or in high-gloss black.
Of course, Aerokit 911 Turbos can be further customized using other Porsche Exclusive-designed parts, including bespoke headlamps and taillights, wheels, and custom paint colors, as seen in the photo above.

As you might have already guessed, the Aerokit Turbo leaves the interior unchanged. That’s not an issue though, as the 911 Turbo is packed with luxury and convenience features, including acres of leather and Alcantara, 18-way adjustable sports seats, aluminum inserts, state-of-the-art technology, a Bose or Burmester sound system, and a wide array of upholstery combinations.

Again, Porsche Exclusive will be more than happy to provide you with unique colors, contrast stitching, carbon-fiber, custom and illuminated door-sill guards, and many more goodies. All you need is a fat wallet.

Both the Turbo and the Turbo S keep their standard drivetrains with the Aerokit, but I have a hunch most Porsche owners won’t mind. That’s because the 911 Turbo packs a raging turbochaged, 3.8-liter, flat-six that generates 520 ponies in standard guise and 560 horsepower in "S" trim The former needs 3.2 seconds to sprint from naught to 60 mph (3.0 seconds with the Sport Chrono pack), while the latter hits the same benchmark in a mind-boggling 2.9 seconds. Top speed sits at 195 and 197 mph, respectively.

Now, Porsche says the Aerokit Turbo is more than just a visual enhancement, with the parts having been put through extensive wind tunnel and track testing at the company’s Devel  opment Centre in Weissach, Germany. As a result, the total downforce generated by the 911 Turbo at 186 mph was increased by 37.4 pounds to 57.3 pounds in the Speed setting, and by 39.6 pounds to 330.6 pounds in the Performance setting. The increased downforce at the front and rear angles increases stability at high speeds.

All told, the Aerokit won’t make the 911 Turbo quicker in a straight line, but it will make it a bit more stable that it already is. Although Porsche has yet to release U.S. pricing information, the Aerokit Turbo will be available on all 911 Turbo and 911 Turbo S models worldwide via Porsche Exclusive. In Germany, it can be ordered for €5,355 including VAT, which converts to $6,108 as of 02/12/2015, with the purchase of a new car. The package can also be retrofitted by Porsche Tequipment for €4,879 ($5,564), excluding paint and assembly. Should the add-ons arrive with the same sticker in the U.S., the 911 Turbo with Aerokit will retail from $157,208, while the upgraded Turbo S will fetch from $188,808. Aftermarket retrofitting will not void factory warranty.
