Add Real Downforce to Your E86 Z4 Coupe
The APR Performance AS-206141 GT-250 Adjustable Wing is a track-focused aero upgrade built for the 2006-2008 BMW Z4 Coupe. The GT-250 uses APR's low-drag 2D airfoil shape, validated with Computational Fluid Dynamics, to deliver consistent downforce across the full span of the wing rather than tapering off toward the tips. For drivers pushing an E86 on track days or autocross, this translates to more confidence at high speed and through fast corners.
Key Features
- 2D low-drag airfoil shape validated using Computational Fluid Dynamics (CFD)
- Consistent downforce distribution across the entire wing span
- Pre-pregnated woven carbon fiber reinforced polymer (CFRP) construction
- Autoclave cured and vacuum bagged in aluminum billet molds for a precise finish
- Gurney flap pre-installed on every AS-206141 GT-250 wing at the factory
- 10 inch chord depth for strong, stable downforce generation
- Aircraft grade billet aluminum pedestals with flat black powder coat finish

About APR Performance
APR Performance designs and manufactures carbon fiber aerodynamic components for street, track, and motorsport applications. Every GT Series wing is developed using CFD analysis and built from pre-pregnated carbon fiber composites in APR's own facility, giving racers and enthusiasts a proven balance of downforce, weight savings, and durability.
FAQ
What is the AS-206141?The AS-206141 is an APR Performance GT-250 adjustable carbon fiber wing built specifically for the 2006-2008 BMW Z4 Coupe and Z4 M Coupe. It uses a 2D low-drag airfoil design with a pre-installed Gurney flap for added downforce.
Will the AS-206141 fit a Z4 Roadster?No. This wing is engineered for the E86 Z4 Coupe body style. Roadster models use a different trunk profile and require a separate wing application.
Is the AS-206141 adjustable?Yes. The GT-250 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-206141 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.
Does the AS-206141 come with a Gurney flap?Yes. Every GT-250 wing, including the AS-206141, ships with a lightweight carbon fiber Gurney flap already installed.
How long does the AS-206141 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-206141 uses aircraft grade 6061 billet aluminum pedestals finished in flat black powder coat for a clean, factory-style appearance.
Can the mounting distance be customized on the AS-206141?APR Performance offers custom pedestal mounting distances on GT-250 wings. Contact our sales team with your specific requirements before placing an order.
Install Instructions
- Confirm trunk lid drilling locations using the APR Performance template or existing factory holes where applicable.
- Mark and drill pilot holes at the marked mounting points, then step up to the final hole size specified by APR.
- Apply touch up paint to the bare metal in each drilled hole to prevent corrosion.
- Position the mounting brackets on the trunk lid and confirm equal spacing side to side before final drilling.
- Install the pedestal studs and mounting hardware, using threadlocker on the studs as recommended.
- Attach the wing airfoil to the pedestals and torque all mounting hardware evenly.
- Set the desired angle of attack, then re-check all hardware for tightness after initial driving.
APR
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, ...
