Does this 67 inch wing for VA WRX STI fit the 2018-2021 STI, or only the earlier cars?

It fits every VA WRX STI from 2015 to 2021. APR lists one GTC-300 wing for the full VA STI run. Confirm your model and model year with us before ordering.

Will it fit a regular VA WRX?

No. This version is for the STI only. APR builds a separate GTC-300 wing for the non-STI VA WRX.

Do I have to drill the trunk?

The vehicle-specific carbon mounting bases are shaped to cover the holes left by the factory STI wing. Final mounting details should be confirmed with the install instructions before work starts.

How much can the wing be adjusted?

The angle of attack adjusts from 0 to 15 degrees on the billet aluminum risers. Lower settings favor top speed, while higher settings add downforce for corners and braking.

Should I choose the 67-inch or the 61-inch wing?

Both use the same GTC-300 airfoil and the same adjustment range. The 67-inch version reaches wider across the STI's trunk for more total wing area, while the 61-inch version keeps a more compact look. The 61-inch wing is a separate listing, linked in the Notes.

What is the PPF film option, and how long does delivery take?

PPF film is an optional extra for an additional $200, chosen at checkout. The wing is made to order or special order from the manufacturer, so we confirm the estimated lead time after you order. Talk to us first if you have a specific deadline.

APR Performance Carbon GTC-300 67″ Adjustable Wing for VA Subaru WRX STI [AS-106766]

The 67 inch wing for VA WRX STI is APR’s GTC-300 carbon fiber adjustable wing, made for the 2015-2021 VA Subaru WRX STI. It replaces the factory wing with a CFD-developed airfoil that adds rear downforce for cornering and braking stability without the drag penalty of a bigger race wing, which suits an STI that splits its time between the street and the track. The angle of attack adjusts from 0 to 15 degrees, so the same wing can run low for high-speed straights or steep for tight, technical circuits. Vehicle-specific carbon mounting bases sit over the factory wing holes, keeping the install clean on the STI’s trunk lid.

CFD-Developed GTC-300 Airfoil

APR shaped the GTC-300 airfoil with computational fluid dynamics (CFD), using a cambered profile that builds a strong pressure difference between the upper and lower surfaces while keeping airflow attached at speed. The result is an 8.8 to 1 downforce-to-drag ratio, giving the STI more rear grip through corners and under braking while giving up very little straight-line speed. The chord varies from 10″ to 12″ across the 67″ span.

Adjustable Angle of Attack

The wing mounts on adjustable 10mm 6061 billet aluminum risers finished in matte black powder coat. Setting a higher angle adds downforce and rear tire load for technical tracks, while a lower angle trims drag for faster circuits and street driving. Because the risers also allow height and position changes, the wing can be tuned to match the rest of the car’s aero setup.

Pre-Preg Carbon Fiber Construction

APR builds the airfoil from pre-preg woven carbon fiber, cured in an autoclave inside aluminum billet molds. That process gives the wing a high strength-to-weight ratio and the stiffness to hold its profile under heavy aero load, so it does not flex at speed and the downforce stays consistent from session to session.

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.
