VERUS ENGINEERING A0148A Rear Diffuser Kit for SUBARU WRX / STI (GR)

Description VERUS ENGINEERING A0148A Rear Diffuser Kit for SUBARU WRX / STI (GR)

The VERUS ENGINEERING A0148A Rear Diffuser Kit is engineered to improve aerodynamic performance and rear-end stability on the Subaru WRX and STI Hatchback (GR). Developed using advanced CFD analysis and in-house 3D scan data, the diffuser is optimized to increase downforce while reducing drag within the available underbody volume. This results in improved aerodynamic efficiency without compromising fitment or ground clearance.

The diffuser features a non-aggressive strake design, providing functional airflow management while maintaining a clean and subtle OEM-like appearance. Precision manufacturing ensures consistent quality, durability, and a near-factory fit and finish. Designed as a fully bolt-on solution, the kit installs without permanent vehicle modification and is suitable for both daily-driven and track-focused applications.

• Reduces rear lift while increasing downforce at speed
