BBi Autosport StreetCup Harness Bar for 982 Porsche 718 Cayman GT4

The BBI Autosport Harness Bar for the 982 GT4 is a result of meticulous design, addressing crucial aspects like harness angle, seat travel, and engine compartment access. The bar is sensibly mounted to the frame structure in the cabin and rear strut towers, providing the strongest mounting points and maximum protection. It utilizes high-strength 4130 chromoly steel tubing for unmatched strength and rigidity. Each joint is carefully TIG welded by hand. The bolt-in installation uses precision CNC turned and milled Inner Diameter Tube Clamps for a perfect fit. This design approach eliminates the need for traditional slip-fit tubes and unsightly through-bolts and nuts, resulting in a bar that is both clean and highly functional.

About BBi Autosport

In the realm of aftermarket tuning, many have sacrificed quality and craftsmanship for cost-effectiveness and convenience. However, this approach contrasts sharply with the ethos of some who prioritize finding premium materials and engaging in meticulous, time-intensive practices. These select few are dedicated to crafting products that embody passion, artistry, and craftsmanship, standing out in an industry often focused on cutting corners.

BBI Autosport, established in the summer of 2005, was born from a mission to reintroduce a sense of artistry and craftsmanship to the exotic tuning market. Founded on a deep-rooted passion and a solid motorsport foundation, BBI Autosport has rapidly risen to prominence in the Porsche industry. The team, boasting over 30 years of collective professional racing experience, leverages this extensive background to fuel the engineering and development of their high-performance parts and services.

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 with any inquiries.
