Upgrade the rear aerodynamics of your 2005–2009 Ford Mustang S197 with the APR Performance GTC-300 Carbon Fiber Adjustable Rear Wing. Designed for motorsports, track use, time attack builds, and high-performance street applications, the GTC-300 delivers substantial rear downforce while maintaining excellent aerodynamic efficiency.
The GTC-300 features a Computational Fluid Dynamics (CFD) developed airfoil profile engineered to improve rear-end stability while minimizing unnecessary drag. Its cambered airfoil creates an effective pressure differential between the upper and lower surfaces, helping maintain airflow attachment and generate consistent downforce at higher speeds.
With a fully adjustable 0°–15° angle of attack, drivers can fine-tune the wing for different tracks and driving conditions. Higher angles increase rear downforce for improved traction, cornering, and braking stability, while lower settings reduce aerodynamic drag for improved straight-line performance.
Constructed from autoclave-cured pre-preg woven carbon fiber and supported by aircraft-grade 6061 billet aluminum risers, the GTC-300 combines lightweight construction, exceptional rigidity, and functional aerodynamic performance.
Important Fitment Note
Fits 2005–2009 Ford Mustang S197 applications.
The vehicle-specific mounting bases are positioned near the outer edges of the trunk lid.
Please verify your trunk and existing spoiler configuration before installation.
Key Features
CFD-Developed Airfoil Design Engineered using Computational Fluid Dynamics to generate substantial rear downforce while minimizing drag.
Adjustable 0°–15° Angle of Attack Allows drivers to fine-tune the aerodynamic setup based on vehicle balance, track configuration, and driving conditions.
8.8:1 Downforce-to-Drag Ratio Optimized to provide strong rear downforce while maintaining aerodynamic efficiency and minimizing unnecessary drag.
Autoclave-Cured Pre-Preg Carbon Fiber Constructed from pre-impregnated woven carbon fiber and autoclave cured in aluminum billet molds for excellent rigidity, durability, and strength-to-weight ratio.
Aircraft-Grade Billet Aluminum Risers Uses high-strength 10mm 6061 billet aluminum adjustable risers for secure mounting and precise aerodynamic adjustment.
Vehicle-Specific Mounting Carbon fiber bottom plates provide a vehicle-specific mounting solution for the S197 Mustang.
Track-Focused Performance The mid-to-large GTC-300 design provides substantial aerodynamic performance without the more extreme aero load of APR's largest wing designs.

Vehicle Fitment
2005–2009 Ford Mustang
S197 chassis
Special Note: Mounting bases sit near the outer edges of the trunk lid.
Optional Carbon Fiber Gurney Flap
An optional Carbon Fiber Gurney Flap is available for additional aerodynamic performance. Mounted along the trailing edge of the airfoil, the Gurney Flap helps increase downforce and reduce airflow separation for additional rear grip during high-speed cornering.

Construction: Pre-preg woven carbon fiber
Attachment: 3M VHB double-sided tape
Why Choose the APR Performance GTC-300?
The GTC-300 sits between APR's smaller and more extreme rear wing designs, making it an excellent option for Mustang owners looking for significant functional downforce without moving to an oversized aero setup.
I really like the way these fit into the curves of the door handles. You can see the quality & craftsmanship that goes into their designs. I’m an extremely happy fan & i’m not easy to make happy. Thanks guys. Job well done. 👍
Everything I’ve bought from these guys has been above board. Their customer service is awesome. Ken is the best. If you ever have any question about anything that’s on their website all you have to do is ask and they’ll respond very fast. I’m a customer for life.
I have made multiple purchases from this company and I have been more than satisfied with every one. They use quality material, it’s always a perfect fit and the packaging for shipping is top notch!! I will buy all of my carbon fiber parts from Carbon Addons!!!
Received the Carbon Fiber Dash Kit and found the pieces carefully packaged and ready for install. After test fitting, installation went smooth and the dash looks so much better! And I really like the way the aluminum dash frames the Carbon Fiber. THANKS!
At first glance , I thoght the horn bezel was ok ! , then it grew on me .. this is a nice piece for my C7 .. it also compliments the rest of my steering wheel pieces
This item makes it easier to see the star switch compared to stock. Great looking item with perfect color, fit and finish.
This is that item you didn’t know you needed till you added it.
Awesome job on such a small item. Thanks!
Really nice small detail with Pop to add some color to the build.
The item was cut a little short on the right side allowing some of the switch to be seen.
Overall very good item. Thanks!
The item looks amazing and fits perfectly.
Easy installation and adds to the custom style of the seat.
The pricing however is quite high for such a small item. Not sure if it cost that much to produce it.
Overall it completes the look we wanted for our show car.
LOVE THESE. From the start packaging was very nice, from box quality to presentation. Shifters are beautiful and high quality. Perfect fit and strong adhesive. 10/10!
Very nice quality, looks amazing.
I get comments from people every time I have my key fob. I have a lot of Carbon Fiber on my car, so it goes good with the accents on the car.
