Understanding Diffusers
What is a Rear Diffuser?
A rear diffuser is a component mounted at the rear of a vehicle, designed to improve aerodynamic efficiency. It works by managing airflow under the car, reducing drag and increasing downforce at higher speeds. This enhanced aerodynamics can lead to better handling and stability.
How Does a Diffuser Work?
Diffusers function by expanding the airflow beneath the vehicle. When the air exits the diffuser, it creates a region of low pressure, which helps to pull the vehicle down towards the road. This effect is crucial for maintaining traction, especially during high-speed maneuvers.

1. Classic Rear Diffusers
The classic rear diffuser, such as the one offered by Street Aero, provides a timeless aesthetic while improving aerodynamics. It typically features a simple design that complements the vehicle’s lines without being overly aggressive.
2. G-Spec Diffusers
Kuruma Z’s G-Spec diffuser is specifically designed for the Infiniti G35 Coupe. This diffuser enhances the rear bumper’s appearance while providing aerodynamic benefits. Its installation requires drilling into the bumper but maintains the car’s structural integrity.
3. JDM Replica Diffusers
Outcast Garage offers JDM Nissan Nismo S-Tune replica diffusers, designed to give your G35 a unique Japanese styling. Made from high-quality carbon fiber, these diffusers not only look great but also perform exceptionally well.
