How adjustable is the APR Performance GTC-300 Carbon Fiber Adjustable Wing?

The angle of attack adjusts from 0° to 15°. Higher angles increase downforce for cornering and braking, while lower angles reduce drag for better straight-line speed. The angle-adjustable risers also allow wing height and position to be fine-tuned.

Which span should I choose, 61" or 67"?

The APR Performance GTC-300 Carbon Fiber Adjustable Wing is offered in a 61" (1549mm) and a 67" (1702mm) span. Contact us to confirm which suits your F82 and your intended use before ordering.

What is the wing made from?

Pre-impregnated woven carbon fiber sheet, autoclave-cured in aluminum billet molds for high density, durability, and resistance to heat and stress-induced deformation. The risers are 10mm aircraft-grade 6061 billet aluminum.

Which BMW does this fit?

The F82 M4. Confirm your exact model year and body style before ordering the APR Performance GTC-300 Carbon Fiber Adjustable Wing.

Description

APR Performance GTC-300 Carbon Fiber Adjustable Wing for F82 BMW M4

The APR Performance GTC-300 Carbon Fiber Adjustable Wing is a high-performance aerodynamics component designed to optimize the aerodynamic balance of performance vehicles, primarily in motorsports and track applications. Engineered for high-efficiency downforce generation with minimal drag, the APR Performance GTC-300 Carbon Fiber Adjustable Wing is tailored for cars seeking improved cornering, braking stability, and high-speed balance.

Construction

The APR Performance GTC-300 Carbon Fiber Adjustable Wing is built from pre-impregnated woven carbon fiber sheet for a high strength-to-weight ratio. It is autoclave-cured in aluminum billet molds, which gives optimal material density, durability, and resistance to heat and stress-induced deformation. Carbon fiber’s natural rigidity prevents flexing at high speeds, so aerodynamic performance stays consistent under heavy loads.

Features

Fully adjustable angle of attack from 0° to 15° for tuning downforce and drag to track conditions
Airfoil shaped through CFD for high-efficiency downforce with minimal drag
Cambered design creates an effective pressure differential across the upper and lower surfaces, keeping airflow attached and limiting flow separation at speed
APR quotes an 8.8 to 1 downforce-to-drag ratio for the wing
Higher angles increase rear tire load for cornering and braking, while lower angles reduce drag for straight-line speed
Angle-adjustable risers in 10mm 6061 billet aluminum allow fine-tuning of wing height and position
Suited to track cars, time attack builds, and street-tuned vehicles
Optional paint protection film
Optional Gurney flap available

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
