Corvette C8 Stingray/Z51 Carbon Fiber Rear Diffuser | VASL Performance

Pre-Preg Carbon Fiber 4-Fin Rear Diffuser Add-On for 2020–2026 Corvette C8 Stingray

Give the rear of your C8 Stingray a wider, sharper, and more aggressive lower profile with the VASL Pre-Preg Carbon Fiber 4-Fin Rear Diffuser Add-On.

Designed for 2020–2026 Corvette C8 Stingray models, with or without the Z51 Performance Package, this one-piece component installs over the factory rear lower valance and extends the rear profile with four integrated vertical fins.

The diffuser is manufactured from Pre-Preg 2x2 3K carbon fiber and finished with a gloss UV-resistant clear coat that highlights the visible twill weave while helping protect the surface from long-term sun exposure.

This product is an add-on rear diffuser. It does not replace the complete factory rear bumper or the entire factory rear valance assembly, and it is not a set of individual carbon fiber fin covers.
