RSC GT Rear Diffuser for Corvette C8 | Cicio Performance

This is NOT a factory replica like the other C8 Corvette Diffusers on the market.  The RSC Carbon Fiber Diffuser is designed and engineered in the United States from a completely blank sheet of paper to exaggerate the look of the OEM diffuser while making subtle changes to the mating sections and mounting tabs in order to improve fitment and the final look of the carbon fiber finish.

This piece installs with OEM like fitment due to our in depth R&D process to reverse engineer the stock C8 Diffuser and design a new more aggressive piece that fits perfectly.  This diffuser installs using all stock C8 hardware and fasteners and requires no cutting, no drilling, or any modification to your Corvette C8


RSC GTC Rear Diffuser for Corvette C8


The Racing Sport Concepts Corvette C8 Rear Diffuser is constructed from the finest pre-impregnated carbon fiber fabrics, utilizing cutting edge epoxy resins to create the lightest, strongest, most beautiful finish possible. It’s impossible to ignore the perfect 3K 2×2 twill weave and that deep clear coat finish we all love.


The Racing Sport Concepts C8 Rear Diffuser is a direct replacement for the OEM rear diffuser, requiring no modifications to the vehicle for installation and is completely reversible.


Our premium UV inhibiting clear coat gives this product a mirror like finish that can be re-polished just like the factory clear coat that came with your vehicle. Over the past ten years, Racing Sport Concepts unique clear coat formula has proven its ability to stand up to the test of time, with thousands of satisfied customers. You can regularly find 8-10+ year old Racing Sport Concepts products making appearances at car shows and events worldwide.
