Aerodynamic performance for every situation
High-speed driving, daily use, and winding roads

Features

• Designed to complement the WRX S4’s versatility, the TYPE-S body kit prioritizes balance across a wide range of driving conditions.
• While optimized for daily usability, the aero design enhances high-speed stability and controllability, delivering confidence without sacrificing comfort.
• The “Smart Sport” design emphasizes the WRX S4’s presence as a refined sports sedan.
• Seamlessly fitting everything from city driving and long-distance cruising to spirited winding-road runs.

Front Bumper Spoiler

• The front spoiler inherits the aggressive styling DNA of HKS’ historic time-attack machines, giving the WRX S4 a bold and purposeful appearance.
• Carbon side vortex panels are integrated at both ends to promote clean airflow management while adding a subtle motorsport accent.
• With a +45 mm extension, the front spoiler enhances visual impact while contributing to improved aerodynamic balance.

Ducktail Spoiler

• The ducktail spoiler improves airflow over the upper surface of the body at high speeds. In combination with optimized airflow beneath the vehicle, it effectively increases downforce, enhancing tire contact and overall driving stability.

Materials

Functionality & Fitment

●Design Using 3D Scanning and 3D CAD

• By combining CFD analysis with advanced 3D scanning and 3D CAD modeling, the aero components are optimally designed for both performance and fitment.
• Designing directly from scanned vehicle data allows for highly accurate fitment, ensuring a precise and seamless installation.
