The new TECHART Aerokit I program for Porsche 911 models explicitly expresses the silhouette and details that characterize the Porsche brand. Inside, you select from high quality materials to customize your automobile for comfort and style. Outside is distinguished by the front spoiler with braking cooling ducts, front grille inserts, side skirts, mirror inserts, and headlight rings designed to accentuate your individuality. Designed in a wind tunnel, the aerodynamics are unrivaled. A roof spoiler and a choice of three different wings (Rear Wing I, Rear Wing III, or Rear Wing IV) offer precise downforce adjustments on the rear axle. For optimum performance, outfit your Porsche with TECHART Formula I, II, or the new light-weight one-piece forged Formula III wheels.
