Corvette C8 Z06 GTZ Rear Diffuser — Carbon Fiber

Take your C8 Z06 or ZR1 to the next level with RSC's GTZ Rear Diffuser—a clean-sheet carbon fiber design engineered for functional downforce and aggressive styling that sets your build apart from the crowd.

The RSC GTZ Rear Diffuser is an original design—not a replica of the factory diffuser. Designed by a former GM Designer with a level of talent usually only available to Big Three manufacturers—you'll find the surfaces of this product match the C8 design language unlike any other product on the market.

The two-piece construction enables easy removal of the bumper cover and utilization of factory mounting locations—no drilling or cutting required for installation. The GTZ Rear Diffuser features an approximately 8-degree angle of attack (depending on ride height and tire pressure) for real aerodynamic benefit, while the split weave centerline delivers that unmistakable supercar aesthetic. Whether you're chasing lap times or turning heads at the local car meet, the GTZ Diffuser delivers the visual impact and functional performance to make your Z06 or ZR1 truly stand out.

Construction & Materials

Manufactured using pre-impregnated (prepreg) 3K 2x2 twill carbon fiber saturated with aerospace-grade epoxy resin, then autoclave-cured under precise pressure and temperature for maximum strength-to-weight ratio. This is the same manufacturing process used on factory Corvette carbon fiber components and produces that high-end supercar fit and finish discerning owners demand. The GTZ Diffuser also utilizes a special high-temperature resin system that resists discoloration and warping not found on lower-cost options. The diffuser features a split weave design joined at the centerline for that unmistakable supercar aesthetic—a detail typically reserved for exotic marques. Finished with a premium UV-inhibiting clear coat that resists hazing and yellowing under harsh sunlight, maintaining that showroom finish for years. The flat, consistent weave pattern achieved through autoclave curing can't be matched by less expensive wet-laid products.

Design & Engineering

The GTZ Rear Diffuser is a clean-sheet RSC design—not a copy of the OEM diffuser. Every detail, from the split weave to the angle of attack, was engineered specifically for the Z06 and ZR1. The two-piece design simplifies installation while maintaining structural integrity. Optional attachment points allow you to reuse your factory mesh grills if desired, giving you flexibility in the final appearance. The approximately 8-degree angle of attack generates functional rear downforce, improving high-speed stability and balance.
