Rear Diffusers & Spats ⁽¹³¹⁾

The Rear Diffusers & Spats collection at Revline features performance aero components that enhance both function and appearance. Rear diffusers improve airflow and reduce drag by managing turbulence under the car, while spats add aggressive styling and complement side skirt or splitter setups. Available in lightweight carbon fiber, durable ABS, and other premium finishes, these upgrades deliver a motorsport-inspired look with real aerodynamic benefits. Our catalog includes direct-fit options for platforms like Subaru WRX/STI, Nissan 370Z, Toyota GR Supra, BMW M-series, and more. At Revline, we stock rear diffusers and spats from trusted brands like APR Performance, ADRO USA, Carbonaddons, and Extreme Online Store so you can complete your aero package with confidence.
