APR Performance Carbon Fiber Rear Diffuser Version 2 for 2014-2019 C7 Corvette

In Stock • Made in the USA • Ships Fast

The APR Performance Carbon Fiber Rear Diffuser Version 2 is a premium direct-replacement upgrade for the 2014-2019 Chevrolet Corvette C7. This high-quality pre-preg carbon fiber diffuser replaces the factory Carbon Flash painted plastic rear diffuser with a lightweight, durable exposed carbon fiber design featuring two vertical fins on each side of the exhaust outlets.

Designed for both style and performance, the Version 2 diffuser helps manage underbody airflow by channeling high-speed air smoothly into the low-pressure wake behind the car. This reduces turbulence, lowers rear lift, decreases drag, and improves overall high-speed stability.

Aerodynamic Performance of the APR C7 Rear Diffuser

Rear diffusers play a key role in vehicle aerodynamics by accelerating and smoothing airflow exiting from underneath the car. The APR Performance Carbon Fiber Rear Diffuser Version 2 improves upon the stock unit by using strategically placed vertical fins to direct fast-moving under-car air into the low-pressure zone behind the bumper.

This design helps reduce both lift and drag, resulting in improved high-speed stability and more confident handling, especially above 100 mph. C7 Z06 and ZR1 owners often report the car feels more planted during highway driving and track sessions.

When combined with a front splitter, side skirts, or rear wing, the diffuser contributes to a balanced aero package that enhances downforce while keeping drag low. Real-world benefits include better traction, reduced rear-end wander, and more efficient high-speed performance.

Easy Installation

Installing the APR Performance Carbon Fiber Rear Diffuser Version 2 is straightforward:

1. Park on a level surface and remove the factory plastic rear diffuser by unbolting it from the lower valance.
2. Test fit the new carbon fiber diffuser to ensure proper alignment with exhaust tips.
3. Install the optional carbon undertray if purchased for extra performance and protection.
4. Bolt the diffuser in place using factory mounting points. Use thread locker and torque to spec (typically 8-10 ft-lbs).
5. Reassemble and test drive to confirm fit and check for clearance or rattles.

No permanent modifications are required. Many owners complete the install themselves in under two hours.
