Perrin Gurney Flap for WRX/STI
The Perrin Gurney Flap adds aggressive styling to your trunk spoiler. The Gurney Flap modification adds slight height to your existing spoiler without being too obtrusive, providing a clean and distinctly modified look. A Gurney Flap is a small tab protruding from the trailing edge of a wing. Typically, this is set at a right angle to the pressure side of the airfoil and protrudes 1% to 2% of the wing chord. This trailing edge device can improve the performance of a simple wing to a level nearly equal to a complex high-performance design.
The Perrin Gurney Flap attaches to the rear wing by drilling holes and bolting it on. Other Gurney Flaps are attached with double-sided tape, which offers a similarly strong mounting; however, the Perrin Gurney Flap is more secure because it is bolted on rather than just taped to the wing, providing extra peace of mind.

Before Ordering
〇 About Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may significantly differ from the automated calculation in rare cases. In such instances, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. We will only provide returns, refunds, or replacement exchanges for damaged items, defective products, or incorrect items if contacted within 7 days of receipt. Please understand that for products sold through us, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located in Japan.
