Techart has revealed a tuning program specifically for the all-wheel-drive Porsche 911 Carrera 4. Visual upgrades include a new nose-lift system that lowers automatically after hitting 37 mph, a carbon-fiber hood and two-part front spoiler, a new rear spoiler, and repositioned side skirts. A set of Formula IV five-twin-spoke alloys, 20 or 21 inches in size, and a new valve-controlled exhaust system are the only chassis upgrades made, while inside, Techart added new leather sports seats, dials, sport steering wheel, and touches of Alcantara and carbon fiber.
