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.
Height: 1/2" (12.7 mm)
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.
If have added the before and after photos. The only reason I didn’t give it five stars is in that the cut out for the parking brake indentation had a carbon fiber cover, which you do have on your whole console replacement. Otherwise, as you can see, it looks great. I would like to order your door handle covers, but since you charge shipping, I will not. I will wait till you have a special on shipping. There should not be any charge for shipping on items over $100 in my opinion.
I was impressed with the quality of the Carbon Hood Vent! As with all of Carbonaddon's products I have ordered, they have been as good or better than advertised!
The product quality is great and the carbon fiber looks good. Installation of the engine bay side covers was very easy, taking less than 15 minutes. As I continue to enhance the look of the engine bay on my 2023 Vette, I will definitely look to carbonaddons for more products.
CarbonAddons products are all top quality! I have outfitted my entire ZR1X with them. All pieces look and fit great! They all match perfectly with Chevy's level2 carbon trim.
The center console is easier to install if you remove it because the gauge cluster is to close to the a/c controls. The fit was perfect and looks factory. No gaps anywhere. Love it!
Literally a perfect fit looks like a factory piece it's very thin so it doesn't protrude and look like you stuck it on there it looks like it's from the factory that he's of his fantastic one of the best products I've put on my car
Great fit and finish looks like a factory stock piece adhesive is very easy and secure it's one of the best pieces on the market and looks like a stock item after applied with easy application
Ive always had a positive experience. I’ve ordered multiple orders and I haven’t been disappointed a single time. Always quality parts, packaged well and shipped fast.
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. 👍
