1997-04 Corvette C5 | EOS Performance Carbon Fiber Rear Bumper Finned Diffuser

Product Overview

Upgrade the rear-end appearance and aerodynamic profile of your 1997-2004 Chevrolet Corvette C5 with this EOS Performance Carbon Fiber Finned Rear Bumper Diffuser, designed to give the C5 a more aggressive, supercar-inspired rear profile while adding the premium exposed-carbon appearance associated with high-performance Corvette builds.

Compatibility: Fits 1997-2004 Chevrolet Corvette C5 models, including applicable Base and Z06 configurations.

This rear diffuser is manufactured from authentic 3K 2x2 twill weave real carbon fiber, combining structural rigidity with an ultra-lightweight footprint. The exposed carbon weave is finished with a glossy clear coat for a deep, premium appearance that coordinates naturally with other Corvette C5 carbon fiber upgrades such as front splitters, side skirts, rear spoilers, and exterior trim.

The diffuser features four prominent vertical aero strakes (fins) that create an aggressive, motorsport-inspired rear profile while helping to manage and channel airflow exiting from beneath the vehicle. Integrated quad exhaust cutouts provide clearance around the rear exhaust area for a clean, finished appearance.

Designed as a direct replacement that mounts to the lower rear bumper area, this diffuser is shaped around the contours of the Corvette C5 rear fascia for a cleaner and more integrated appearance than universal diffuser add-ons.

This 1997-2004 Corvette C5 Carbon Fiber Finned Rear Diffuser is ideal for owners looking to sharpen the rear-end styling of their C5 with a genuine carbon fiber aerodynamic upgrade suitable for street, show, and performance-focused builds.
