ZACOE Performance Carbon Rear Diffuser for G14 / G15 BMW 840i and M850i

ZACOE Performance’s carbon fiber rear diffuser for the BMW 840i and M850i combines cutting-edge design with precision craftsmanship, enhancing the 8 Series’ aerodynamics and visual appeal. Expertly engineered with ZACOE’s signature expertise, the diffuser adds a bold, race-inspired aesthetic while improving airflow and stability. With meticulous attention to detail and a focus on functionality, it transforms the rear profile of the BMW 840i and M850i, delivering a perfect fusion of elegance and performance.

3D Scanning

After finalizing the model and concept, ZACOE Performance obtains an OEM car and performs a detailed 3D scanning process to generate a precise digital model. Using advanced scanning technology, the exact dimensions and contours of the car’s exterior are captured, forming the foundation for the design. This stage, which takes over 40 hours per car, is crucial for integrating sophisticated inner mechanisms and achieving flawless bolt-on fitment.

Digital Design & Testing

Once the digital model is complete, ZACOE Performance designers conduct brainstorming sessions to create initial concepts through hand-drawn sketches. These sketches are transformed into computer-aided design (CAD) software, where the boldest ideas are refined and brought to life. The draft designs undergo preliminary aerodynamic testing using cutting-edge software, ensuring the results meet the highest standards of quality, innovation, and precision.

Prototyping

With the digital design validated, ZACOE Performance proceeds to build a physical prototype of the kit using ABS material. Components are fabricated with specialized equipment such as 3D printers and CNC machines. The assembled prototype is then rigorously tested on the car to confirm proper fitment and performance.

Mold-making

Following successful prototype testing and any required refinements, ZACOE Performance begins crafting molds for the carbon fiber kit. Each mold, created using the prototype as a template, is meticulously produced with a combination of skilled craftsmanship and advanced machinery. This process culminates in a sleek, lightweight carbon fiber kit that enhances the vehicle’s aesthetics and performance capabilities.

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.
