APR Performance designs and manufactures carbon fiber aerodynamic components for street, track, and motorsport applications. Every GTC Series wing is developed using CFD analysis and built from pre-pregnated carbon fiber composites in APR's own facility, giving drivers a proven balance of downforce, weight savings, and durability.
The AS-106121 is an APR Performance GTC-300 adjustable carbon fiber wing built specifically for the 2016-2019 Cadillac ATS-V Coupe. It uses a 61 inch span 3D airfoil design for strong, CFD-validated downforce.
Will the AS-106121 fit an ATS-V Sedan?No. This wing is engineered for the ATS-V Coupe trunk profile. The Sedan uses a different trunk lid shape and requires a separate mounting application.
Is the AS-106121 adjustable?Yes. The GTC-300 wing allows angle of attack adjustment so you can fine tune downforce and drag based on track conditions and driving style.
What material is the AS-106121 wing made from?The airfoil is constructed from pre-pregnated woven carbon fiber reinforced polymer, cured in an autoclave using aluminum billet molds for a lightweight yet durable finish.
What is the difference between the GTC-300 and GT-250 wing lines?The GTC-300 uses a 3D airfoil shape for higher downforce applications, while the GT-250 uses a 2D airfoil design. Both are CFD validated, but the GTC-300 is generally the more aggressive aerodynamic option.
How long does the AS-106121 take to ship?This wing is made to order with a normal lead time of 2 to 3 weeks. Contact our sales team for current availability before ordering.
What are the mounting pedestals made of?The AS-106121 uses aircraft grade 6061 billet aluminum pedestals, 10mm thick, finished in flat black powder coat for a clean, factory-style appearance.
Does the AS-106121 require drilling into the trunk lid?Yes. Installation requires drilling mounting holes in the trunk lid at the pedestal locations specified by APR Performance.
APR Performance has manufactured aerodynamic carbon fiber components since 1999, developing front splitters, rear wings, side splitters, canards, diffusers, and hood vents through Computational Fluid Dynamics analysis and real-world track validation. APR's pre-preg carbon fiber construction produces parts that are lighter and structurally stronger than wet-layup alternatives, delivering aerodynamic downforce improvements on track-driven and time attack vehicles. Popular APR Performance Carbon Fiber Products APR Performance's catalog includes GTC series adjustable rear wings in widths from 200mm to 600mm, front air dams and splitter extensions, carbon fiber side splitters and side skirts, rear diffuser panels, hood vents for engine bay heat extraction, carbon fiber mirror caps and trim pieces, and carbon fiber brake cooling ducts for track applications. APR products are available for a wide range of sports cars, performance sedans, and track-focused platforms including Honda, Acura, ...
