The super aramid black shell uses high-strength aramid fiber for a stiffer and lighter alternative. Both options are FIA approved.

What makes the ZETA IV different from previous ZETA models?

The ZETA IV introduces a newly designed shell shaped to better conform to the driver's body, improving holdability and comfort over its predecessors.

BRIDE ZETA IV Bucket Seat

Upgrade your driving experience with the BRIDE ZETA IV Bucket Seat, a race-inspired seat engineered for superior support, safety, and comfort. As the latest evolution of BRIDE’s renowned ZETA series, the ZETA IV features a reinforced shell construction that enhances rigidity while maintaining a lightweight design. Its ergonomically optimized shape is designed to properly support the driver’s body, improving stability during high-performance driving and reducing fatigue over long sessions. High-quality cushioning provides added comfort without sacrificing hold, making it suitable for both street and track use. Manufactured in Japan with strict quality standards, the ZETA IV delivers a perfect balance of durability, precision, and motorsport-focused design.

New Standard Model

The BRIDE full bucket seat has been designed with ergonomics and the human skeleton in mind, creating a standard shape. With the knowledge gathered from their ZETA series, they have developed an updated version of it known as ZETA IV which can be installed on various types of vehicles for all kinds of competition categories.

Advanced Material and Manufacturing Method

The FRP shells, which up until now have been composed of glass fiber and aramid fibers, are now reinforced by the addition of high–performance materials. This has resulted in a 15% increase in shell rigidity. In order to enhance comfort and durability during extended drives, newly molded urethane is being employed for both seat cushions as well as thigh cushioning that come into direct contact with the body.

Shell Design and Hold Performance Considering Safety

The new shell shape and vertical slits on the back cushion make it easier for the headrest to fit in with your back, shoulders, allowing you to maintain an optimal driving position over a long period of time. The design also helps raise up one‘s thighs which avoids sinking forward during hard braking or a collision accident – known as “submarine phenomenon“.

LOWMAX System Is Used In ZETA Series

The shoulder size has been decreased to 560mm and the LOWMAX system, which had only previously been used for some full bucket seats and reclining seat models, was implemented in ZETA. This enabled “seat center = handle center“ design that would have otherwise not be possible with traditional designs to become achievable across a wider range of vehicle types.

This Is The Latest Model of The ZETA Series Which Has Won Many Races Since It’s Launch In 1990 and Has Kept The Driver’s Safety

After a 16–year gap, the BRIDE full bucket seat – which caters to all kinds of drivers, from everyday road users to circuit and competition racers – has been updated. The new ZETA IV is the latest model in its series and boasts an ergonomic shell design ideal for multiple uses; it can be used on roads as well as during intense sports driving activities. Thanks to decades of experience with sheet metal manufacturing technology along with high–performance materials employed in each part, this cutting edge product provides superior holdability, comfort levels durability and safety compared to regular models available today.
The Shell Material Can Be Selected From Two Types : FRP silver shell and Super aramid black shell.
The Color Variation Can Be Selected From Three Types : Gradation logo, Black and Red.
The ZETAIV is a FIA approved model.

ZETA Series Has Evolved Greatly By Gathering BRIDE Technology and Experience

The LOWMAX system, which has been incorporated into some seats as well as featuring large belt holes and durable PVC leather, has enabled the racing sport seat to develop into one that is capable of being used for extended periods in a greater variety of vehicle types and categories.

FIA Approved and Conformity To The Safety Standard

ZETA IV meets the safety standards laid out in Japan‘s Road Transport Vehicle Act, which is used for car examinations. Furthermore, it has also been certified with FIA8855–1999 standard set by the International Automobile Federation and can be employed as a legitimate vehicle in international competitions or races. Thanks to its design and quality that surpasses even tougher tests, ZETA IV stands tall when it comes to ensuring top level of security.

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.
