Maximize the aerodynamic efficiency of your Chevrolet Corvette C8 Stingray with the APR Performance Carbon Fiber Rear Diffuser. Designed to work in harmony with other aerodynamic components such as front splitters, side rocker extensions, and rear wings, this functional diffuser helps optimize underbody airflow for improved stability and performance.
As air travels beneath the vehicle at high speed, it accelerates before exiting at the rear. The APR Rear Diffuser is engineered to manage this airflow transition by directing the high-speed air into the low-pressure zone behind the vehicle. This reduces turbulence, enhances airflow efficiency, and helps generate additional rear downforce for improved traction and high-speed stability.
Manufactured using autoclave-cured pre-preg carbon fiber, the diffuser delivers exceptional strength, lightweight construction, and premium fitment while adding an aggressive motorsport-inspired appearance to your Corvette.
Whether you're upgrading your street car or building a dedicated track machine, the APR Performance Rear Diffuser is a functional aerodynamic upgrade designed to improve both performance and styling.

Customer Reviews
Overall rating: 4.8 / 5 from 5060 reviews.
I have added a ton of pieces on the interior, from the console, waterfall, speakers, door, overhead, garage buttons and the steering wheel which I highly recommend. My car is six years old and the oyster gray isn't holding up or able to clean up, so these pieces really dressed up my interior to the next level or two! Thank uou Carbonaddons!!!!
Fast service. High quality. Easy installation. Followed reviews and recommendations to test fit and heat the adhesive first. Next plan is for a splitter and door side skirts!
The first photo is the before, the second is the passenger side that looks great. Where I am disappointed in is the drivers side, if you look at the top it does not cover the original completely at the top and some of the silver shows thru. A fraction more carbon material and it would be great. That is disappointing and why I only rated it as 3 stars.
Swapping the buttons and wiring over from the stock steering wheel takes some patience, but the finished look is absolutely worth it. This F1-style wheel from Carbon addons gets A LOT of attention at car shows and really stands out in my C8. Haven’t seen anyone else with one… YET! 🤞
Ordering from Carbon Addons has been a thrill ride for my cars. You guys rock!! Keep up the hard work and dedication to your customers. Oh and your car air freshener is awesome! Love the manly smell.
