Is the BRIDE ZIEG IV WIDE FIA approved?

Yes. The BRIDE ZIEG IV WIDE is a FIA approved model across all shell and color variations. FIA homologations carry expiration dates, so verifying the seat's current approval status against the FIA's active homologation list before use in sanctioned competition is recommended.

How much wider is the ZIEG IV WIDE compared to the standard ZIEG IV?

The ZIEG IV WIDE is 30mm wider at the thigh section and 10mm wider at the shoulder section compared to the standard ZIEG IV. These dimensional increases are designed to provide a proper fit for larger-framed drivers without altering the deep hold geometry or round shoulder line that defines the ZIEG IV shell design.

Who is the ZIEG IV WIDE designed for?

The ZIEG IV WIDE is designed for larger-bodied drivers who require more room at the thigh and shoulder sections than the standard ZIEG IV provides. It retains the same deep hold construction and high-G cornering support as the standard model, making it equally suited to performance driving and competition use; the only difference is the wider shell dimensions for driver accommodation.

What shell material options are available for the ZIEG IV WIDE?

The ZIEG IV WIDE is available in two shell options: an FRP silver shell and a super aramid black shell. The FRP shell uses fiberglass-reinforced plastic construction for a durable and proven build. The super aramid black shell uses high-strength aramid fiber for a stiffer and lighter alternative. Both options are FIA approved.

What color options does the ZIEG IV WIDE come in?

The BRIDE ZIEG IV WIDE is available in three color variations: gradation logo, black, and red. All color options are available across both shell material choices and all carry FIA approval.

How does the ZIEG IV WIDE perform under high-G cornering conditions?

The ZIEG IV WIDE shares the same deep hold shell geometry as the standard ZIEG IV, featuring a rounded shoulder line that wraps around the driver's upper body and a contoured thigh section that secures the lower body under load. This construction keeps the driver firmly in place during high-speed cornering and situations where significant lateral G-force is applied, supporting reliable and precise driver inputs throughout.

What is the difference between the ZIEG IV and the ZIEG IV WIDE?

The ZIEG IV WIDE is a dimensional variant of the standard ZIEG IV, sharing the same shell design, deep hold construction, round shoulder line, shell material options, color choices, and FIA approval. The difference is the wider thigh section, 30mm larger than the standard model, and the wider shoulder section, 10mm larger than the standard model. Drivers who find the standard ZIEG IV fits correctly should choose the standard model; drivers who need more room at the thighs or shoulders should consider the WIDE.

BRIDE ZIEG IV WIDE Bucket Seat

Maximize support and comfort with the BRIDE ZIEG IV WIDE Bucket Seat, a race-inspired seat designed specifically for drivers who require a roomier fit without sacrificing performance. Featuring a wider shell design, it provides additional space in key areas while maintaining the deep, wraparound structure needed to keep the driver securely positioned during aggressive driving. Constructed with a high-rigidity yet lightweight shell, the seat delivers excellent strength and durability for both street and track use. Its ergonomic design promotes proper posture and reduces fatigue, while high-quality cushioning ensures lasting comfort. Handcrafted in Japan with BRIDE’s renowned attention to detail, the ZIEG IV WIDE offers a perfect balance of safety, fitment, and motorsport-focused performance.

Low Position Essential For Circuit and Sports Driving

ZIEG IV has set up the BRIDE–patented LOWMAX system. Additionally, the backrest has a curved form, allowing the head position (eye point) to be lowered. This seat is perfect for more intense situations, for example racing on a track

Advanced Material and Manufacturing Method

The FRP shells that have been employed up to now have been reinforced with the inclusion of additional high–grade materials (glass fiber and aramid fiber), improving their rigidity by 15%. Moreover, the seat cushion and thigh cushion, which are in contact with the body, have been updated to molded urethane to create a more comfortable and longer–lasting driving experience

Shell Design and Hold Performance Considering Safety

The shell shape and vertical slots in the back cushion are designed to enhance the fit of the headrest to the back, shoulders and to keep the driver in the right position for an extended period of time. Furthermore, the shape of the thigh lift helps to stop the “submarine phenomenon“ that can occur during hard braking or in the case of a collision

Adopted Large Seat Belt Holes

The ZIEG IV now includes the same large seat belt hole which was previously featured in the ZETA III PLUS and XERO series. This adjustment allows for a much wider range of compatibility with a variety of racing harnesses and FHR systems (head and neck protection devices), taking into account the various heights of individual drivers and the height of their seating position

The Wide Model Full Bucket Seat 30mm Larger Than The Standard Model

The ZIEG IV WIDE is an advanced version of the standard ZIEG IV bucket seat. It has been designed to provide higher safety standards and improved performance based on the experience of professional racers and their feedback. It features 30mm wider thigh and 10mm wider shoulder area than the original ZIEG to make it suitable for drivers of larger body shapes. The entire seat shell is the same as the ZIEG IV, with a deep hold shape and round shoulders line to ensure the driver is firmly held in place even when high–speed cornering or driving G forces are applied
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 FIA has approved the ZIEG IV WIDE as a model

LOWMAX For Wide Models Too

BRIDE‘s patented LOWMAX system is employed on the wide model, allowing the seating position and eye point to be reduced. Even people of a larger body type can obtain the perfect driving position for sporty driving

FIA Approved and Conformity To The Safety Standard

The ZIEG IV WIDE meets the safety requirements of the Japanese Road Transport Vehicle Act for cars. Moreover, it has earned the FIA8855–1999 standard set by the FIA (International Automobile Federation), allowing it to be used for international formal races and competitions. It is equipped with a high level of protection thanks to its design and quality that surpasses even the toughest testing standards

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.
