Diffusers work in conjunction with other aerodynamic components of a car to help produce downforce. Because a car displaces air as it moves forward, the air molecules in the rear of the car get disrupted causing a vacuum of low pressure air.
To help channel the high speed air flow coming from underneath the car, diffusers redirects the high speed air flow to transition smoothly transition into the low pressure vacuum in the rear. This encourages a smoother flowing air flow underneath the car and allows better performance from other aerodynamic components such as aerodynamic wings.
APR Performance has manufactured aerodynamic carbon fiber components since 1999, developing front splitters, rear wings, side splitters, canards, diffusers, and hood vents through Computational Fluid Dynamics analysis and real-world track validation. APR's pre-preg carbon fiber construction produces parts that are lighter and structurally stronger than wet-layup alternatives, delivering aerodynamic downforce improvements on track-driven and time attack vehicles. Popular APR Performance Carbon Fiber Products APR Performance's catalog includes GTC series adjustable rear wings in widths from 200mm to 600mm, front air dams and splitter extensions, carbon fiber side splitters and side skirts, rear diffuser panels, hood vents for engine bay heat extraction, carbon fiber mirror caps and trim pieces, and carbon fiber brake cooling ducts for track applications. APR products are available for a wide range of sports cars, performance sedans, and track-focused platforms including Honda, Acura, ...

Rear diffusers manage airflow under the vehicle to reduce drag and generate downforce at the rear axle, improving high-speed stability and traction for performance cars, track builds, and custom street machines. Available in polyurethane, fiberglass, and carbon fiber, diffusers pair with splitters and side skirts to create a complete aerodynamic package.Popular Diffuser UpgradesTop options include polyurethane OEM-style replacement diffusers for Mustang, Camaro, Challenger, and WRX platforms, aggressive three-fin and five-fin carbon fiber diffusers for track day and time attack builds, and widebody-compatible diffuser extensions for stanced and show vehicles. Many applications accept bolt-on installation using factory undercarriage mounting points without cutting or modification.Do rear diffusers improve performance or just looks?A properly designed diffuser accelerates underbody airflow to create a low-pressure zone that pulls the rear of the car toward the ground, generating rear ...
