JCR Rear Wing Uprights for 982 Porsche 718 Cayman GT4 RS

The JCR Rear Wing Uprights for the 982 Porsche 718 Cayman GT4 RS are offered in two advanced material options — Billet Aluminum and 3D‑Printed Titanium. The Billet Aluminum uprights are precision‑machined from high‑grade aluminum, providing improved strength, durability, and an expanded range of rear wing adjustment. Finished in either raw or black with titanium fixings, they are engineered for seamless compatibility with the OEM GT4 RS rear wing. The 3D‑Printed Titanium uprights leverage cutting‑edge additive manufacturing and high‑strength titanium to achieve substantial weight savings over the factory components while delivering superior rigidity and performance. Also available in raw or black finishes, these uprights optimize aerodynamics and handling while enhancing the car’s appearance. Both options serve as direct replacements for the OEM uprights, offering straightforward installation and a premium performance‑focused upgrade for the 718 Cayman GT4 RS.

Optimized Aero

  • The 718 GT4 RS features a significantly larger rear wing element than the 981 GT4 or 718 GT4. This wing produces more downforce and is top-mounted for greater efficiency. JCR Wing Uprights are designed as a 100% direct fit, allowing seamless installation of an OEM GT4 RS rear wing in a more optimized position (up and back) compared to the factory placement on the 718 GT4 RS. The revised wing position enhances the efficiency of the factory rear wing, increasing effectiveness for improved aero balance with a lower angle of attack (AOA) and reduced drag. Additionally, the base AOA is adjusted to provide a wider range of aggressive settings, enabling more front-end downforce when paired with JCR’s upcoming front aero solutions.

CNC Billet Aluminium Construction

  • At the start of the project, JCR defined clear design criteria and performance goals for the JCR Billet Aluminium Wing Uprights. Multiple subtle design features were incorporated, and while each detail may be minor on its own, together they create an exceptional end result. This level of attention to detail reflects JCR’s commitment across the entire product line.
    • Improved aero performance & increased aero efficiency
    • Stiffer & stronger vs OEM wing uprights
    • Weight reduction vs OEM wing uprights
    • OEM+ design language
  • The JCR Billet Aluminium Wing Uprights are machined from 6082‑T6 aluminium on a state‑of‑the‑art 5‑axis CNC. These uprights are stronger, stiffer, and lighter than the factory components, offering a true performance upgrade with weight savings. They are offered in raw or black finishes and include Billet Titanium Fixings, providing lightweight, high‑strength, and corrosion‑resistant hardware.

High-Tech 3D Printed Titanium Construction

  • Similarly, at the start of the project, JCR established specific design criteria and goals for the JCR 3D Printed Titanium Wing Uprights. Each piece integrates multiple small yet purposeful design features, which collectively deliver an exceptional finished product. This meticulous approach is a signature of JCR’s engineering philosophy.
    • Ultimate solution utilizing cutting edge technology
    • Improved aero performance & increased aero efficiency
    • Stiffer & stronger vs OEM wing uprights
    • Weight reduction vs OEM wing uprights
    • OEM+ design language
  • For those seeking maximum innovation, JCR produces the 3D Printed Titanium Wing Uprights using advanced titanium additive manufacturing. This process enables a unique hollow internal structure, reducing mass by 27% compared to OEM uprights while improving stiffness and strength. These uprights are lighter, stronger, and more rigid than the factory parts, further enhancing vehicle performance. They are available in raw or black finishes and are supplied with Billet Titanium Fixings for superior durability and corrosion resistance.

Weight Savings

  • One of the key design objectives for the JCR Wing Uprights was achieving weight reduction despite their larger dimensions. The JCR Billet Aluminium Wing Uprights achieve a 0.44kg weight savings, providing a measurable performance benefit with zero weight penalty.

Direct Replacement

  • The JCR Wing Uprights are a direct replacement for the OEM components, utilizing factory mounting points. JCR focuses on delivering an OEM+ aesthetic for all exterior modifications, ensuring these upgrades integrate seamlessly with the vehicle’s factory design while improving aerodynamic performance.

Features

  • Full CNC billet aluminium or 100% 3D-printed hollow titanium construction options
  • 100% direct replacement
  • Improved rear stability
  • Larger range of adjustment
  • Choice of raw or black finish
  • Titanium fixings

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.
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.
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.
