Product Features
-
Lowered Aerodynamic Stance: Accentuates the side profile of your VA WRX / STI by extending the lower rocker sill downward and outward for an aggressive, track-inspired aesthetic.
-
Durable Polypropylene Construction: Injection-molded from resilient, high-impact polypropylene (PP) formulated to flex over curbs and resist cracking, chipping, and road debris impacts.
-
Unpainted Matte Black Finish: Arrives in a clean, raw matte black finish that can be mounted directly for a contrasting textured look, wrapped, or prepped and painted to match factory exterior colors.
-
Airflow Stabilization: Directs lateral air smoothly along the vehicle’s wheelbase, reducing turbulent air intrusion underneath the chassis to improve high-speed driving stability.
-
Precision VA Chassis Fitment: Digitally molded from 3D laser scans of the 2015-2021 VA platform to ensure flush edge-to-edge alignment beneath factory OEM rocker moldings.
-
Lower Rocker Sill Defense: Protrudes slightly along the lower door line to serve as a protective barrier against gravel, tire spray, and roadway hazards.
