VERUS ENGINEERING A0028A Rear Diffuser Kit for SUBARU WRX / STI (VA)
Description VERUS ENGINEERING A0028A Rear Diffuser Kit for SUBARU WRX / STI (VA)
The VERUS ENGINEERING A0028A Aggressive Rear Diffuser is engineered for the Subaru WRX / STI (VA) to deliver increased aerodynamic performance with a more pronounced visual presence. Developed using advanced CFD analysis and in-house scan data, the diffuser increases rear downforce while reducing drag within the available packaging volume, improving overall vehicle stability at speed.
The aggressive strake design is intended for owners seeking both functional aerodynamic gains and a bold rear-end appearance. Precision manufacturing and vehicle-specific development ensure near-OEM fit and finish. The diffuser contributes to improved tire grip at higher speeds and supports a balanced aerodynamic profile when paired with other Ventus 1 components.
- Reduces aerodynamic drag
- Decreases lift to increase rear downforce
- Improves overall aerodynamic efficiency
- Enhances tire grip and stability at speed
- Simple, non-invasive bolt-on installation
Specifications:
- Design Optimization: CFD optimized
- Material: 5052-H32 sheet aluminum
- Manufacturing: CNC laser cut and CNC press brake bent
- Finish: Powder-coated low gloss textured black
- Hardware: Stainless steel
- Construction: Unique strake-to-mainplane design
- Country of Origin: Made in the U.S.A.
