Rear Diffusers for the 2014-19 Chevrolet Corvette C7: finned rear diffusers, diffuser fin extensions and full bumper-integrated diffusers in carbon fiber and ABS. The diffuser finishes the rear view and pairs with your exhaust tips and spoiler. Everything on this page is confirmed for C7 fitment.
Grand Sport and Z06 share the wide body, so most Z06 aero fits Grand Sport directly; Stingray is narrow body; ZR1 has its own front end and wing. This page covers Grand Sport, Z06, Stingray and ZR1; use the Model filter on the left to see only parts for your trim.
Materials run carbon fiber and ABS plastic, with finishes such as Carbon Fiber, Carbon Flash, Hydro-Dipped Carbon and Primer Black. Carbon fiber parts are UV clear-coated; ABS parts ship primed or finished as listed.
