Corvette C8 Apex GT3 100% Pre-Preg Carbon Fiber Rear Diffuser (Fits All Models)

Transform the rear aero balance and aerodynamic efficiency of your mid-engine supercar with the C7 Apex GT3 100% Pre-Preg Carbon Fiber Rear Diffuser. Engineered as a pure motorsport undertray solution and validated through extensive Computational Fluid Dynamics (CFD) simulations, the Apex GT3 edition features aggressive, deep-channel aerodynamic expansion strakes and full-length underbody extraction tunnels designed to fit all 2020+ C8 Corvette models. While standard aftermarket diffusers require separate configurations for narrow and widebody chassis, the Apex GT3 utilizes precision 3D CAD modeling to deliver seamless, universal fitment across the Corvette C8 Stingray, Z51, Z06, E-Ray, Grand Sport, and ZR1. Handcrafted from 100% aerospace-grade pre-preg (dry carbon) carbon fiber cured in an autoclave, each diffuser achieves maximum torsional rigidity under intense exhaust heat and heavy downforce loads. Engineered with a specialized dual-finish architecture, the upper bumper-mounted shell is finished in an automotive UV-resistant high-gloss clear coat, while the functional lower undertray and deep strakes feature a high-durability, heat-resistant structural epoxy finish to withstand direct radiant exhaust heat and track blast.

CFD-Tested Aerodynamic Performance: 30 m/s (67.11 mph): 43.20 lbs Downforce | 3.85 lbs Drag 60 m/s (134.22 mph): 172.80 lbs Downforce | 15.41 lbs Drag 80 m/s (178.96 mph): 307.20 lbs Downforce | 27.39 lbs Drag 90 m/s (201.32 mph): 388.79 lbs Downforce | 34.66 lbs Drag Key Features & Benefits: CFD-Validated Downforce Generation: Generates up to 388.79 lbs of functional rear downforce at 201 mph while adding only 34.66 lbs of aerodynamic drag. 100% Pre-Preg Autoclave Cured Construction: Aerospace-grade dry carbon ensures maximum structural stiffness, ultra-light mass, and uniform 2x2 twill weave alignment. Performance Dual-Finish Architecture: Upper body shell finished in high-gloss UV clear coat; lower functional expansion tunnels finished in durable structural epoxy. Universal Fitment Across All C8 Trims: Direct bolt-on compatibility engineered for Stingray, Z51, Z06, E-Ray, Grand Sport, and ZR1 models. Deep-Channel Expansion Tunnels: Extended vertical aero strakes prevent turbulent cross-draft air from entering the low-pressure underbody stream, optimizing ground effect suction. High-Temp Exhaust Heat Resistance: High-temp resin formulation handles extreme radiant heat from factory center-exit or aftermarket exhaust systems.
