Your search for the ultimate wing uprights is over.
Exclusively available through Future Classic and IND Distribution, Fall-Line has leveraged their extensive racing experience to develop a GT4 6061-T6 aluminum wing mount set for track-oriented BMWs equipped with M235iR / M240iR / GTS wings.
Fall-Line’s uprights feature gusseting to increase strength. As a result, they achieve a slim profile without sacrificing rigidity, contributing to a lightweight design. Despite being more than 5 inches taller than the factory GTS mounts, the Fall-Line GT4 uprights weigh the same and are nearly half the weight of competitor products.
Mounting the wing higher allows it to interact with cleaner airflow, generating up to 8 pounds of downforce per pound of drag. While other mounts boast a similar height, the Fall-Line uprights also feature four mounting holes for adjusting the fore-aft position of the wing. The further back the wing is mounted, the greater the ground effect and leverage become, further enhancing the wing's downforce effectiveness and allowing for a wider range of applications.

Before You Order
〇 About Import Consumption Tax
At Shaftoya shopping site, we cover 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 Checking Compatibility
All product databases are based on North American vehicles (USDM), so please verify whether installation on Japanese vehicles (JDM) is possible before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you 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 in the tabs on our top page, this does not guarantee that they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. For shipping estimates, please enter your delivery address on the checkout page to have it calculated automatically. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are 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 when ordering. If you are in a hurry, please contact us to confirm delivery times in advance. All products are transported via air freight. No products are shipped by 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" (Shaken), and we cannot provide strength calculation documents for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off public roads," 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 packing box or the product. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or incorrect items. Please note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
