100% OEM Authentic Nissan Parts
💎 The Legacy Component: Advanced Aero Engineering
P/N: 748A0-AA400 + 748A2-RSR45
The Nissan Skyline GT-R V-Spec ("Victory Specification") designation was earned through advanced aerodynamic engineering, and this component is the cornerstone of that legacy.
This is a Genuine OEM Nissan/NISMO rear diffuser assembly—the exact component that allowed the V-Spec R34 to achieve record-setting times by managing airflow beneath the chassis, reducing drag, and providing critical high-speed stability and downforce.
This assembly is the original Advanced Aero specification unit developed by Nissan’s finest engineers and track-tested by NISMO. It integrates seamlessly with the chassis floor, working in conjunction with the front diffuser to create a fully managed underbody airflow. This critical function reduces turbulent air behind the vehicle and ensures the lowest possible coefficient of drag for maximum stability at high speeds.
Perfect for the discerning collector or builder prioritizing period-correct components, this is more than a body kit piece—it is a verifiable piece of automotive history.
Authenticity Genuine OEM Nissan / NISMO Component Collector Grade: Guaranteed factory fitment and quality.
Material Hand-Laid Carbon Fiber Construction Lightweight, high-rigidity construction utilized on V-Spec and N1 models.
Function Advanced Aerodynamics (Venturi Effect) Dramatically increases airflow velocity beneath the car, creating effective downforce.
Assembly Complete Diffuser & Fin Assembly Includes all primary carbon sections and plastic-injected aero fins (OEM PN-stamped).
Rarity Special Order / Limited Production Produced only for the limited-run V-Spec and N1 models; a continuously sought-after part.
Identification Unique Serialization Each unit carries a specific serialized production number for absolute authenticity (e.g., CP-119052416).
Compatibility Nissan BNR34 Skyline GT-R V-Spec / V-Spec II / N1 Direct bolt-on replacement using factory mounting points. (May require V-Spec Triple Cross Bar for installation on Non-V-Spec GT-Rs).
