Understanding the Purpose of a Rear Diffuser

When I first considered upgrading my G37 Coupe, I quickly learned that a rear diffuser serves multiple purposes. Primarily, it enhances aerodynamics by managing airflow under the car, which can improve stability at high speeds.

I set a budget that allowed for a quality product without breaking the bank. It’s essential to balance quality and cost, ensuring that I wasn’t sacrificing performance or aesthetics for a lower price.
