Aerodynamics for Ford Performance models (ST & RS)

The Ford Focus is a mainstay in the tuning scene. Our product range for the Focus ST and the powerful Focus RS leaves nothing to be desired.

  • Focus Mk3 (ST & RS): For the third generation, we offer huge rear diffusers ("RS look" also for the ST) and spoiler attachments. Please pay close attention to whether you drive the facelifted (Mk3.5) model !
  • Focus Mk4 ST: For the current model, we have developed very angular, modern front lips (V.1 to V.4) that emphasize the sharp front end.
  • Racing Durability: Many parts for the Focus are available in our "Street Pro" version – extremely durable and with a cool, milled edge look.
