Seibon RD0607SBIMP OE-Style Carbon Fiber Rear Diffuser

The Seibon RD0607SBIMP is an OE-style carbon fiber rear diffuser engineered to enhance both the aerodynamic performance and exterior styling of your Subaru Impreza, WRX, or STI sedan. Designed to channel underbody airflow for an efficient rear exit, this diffuser adds functional downforce while delivering a race-inspired appearance straight from the factory.

Constructed from premium French or US-made carbon fiber, each diffuser is hand-crafted using a one-piece carbon sheet that ensures a uniform, consistent weave pattern across the entire surface. Seibon's proprietary production process achieves an exceptional carbon-to-resin ratio, resulting in a part that is both lightweight and exceptionally rigid.

Key Features:

• OE-style design for a factory-correct, seamless appearance
• Hand-crafted from premium French or US-made carbon fiber
• Consistent weave pattern via one-piece carbon sheet construction
• Optimized carbon/resin ratio for high stiffness and structural strength
• High-gloss UV-resistant clear coat finish that resists chipping and flaking
• Bolt-on installation — mounts directly to chassis
• Rigorously inspected through Seibon's multi-step quality control process
• Compatible with Subaru Impreza / WRX / STI Sedan (GDA, GDB, GDF chassis)

Each component is individually inspected before leaving the facility and is backed by Seibon's limited manufacturer warranty. Whether you're building a dedicated track car or simply upgrading your street build's aerodynamics, the Seibon RD0607SBIMP delivers proven performance with a premium finish.
