Is the BRIDE ZETA IV CLASSIC FIA approved?

No. The BRIDE ZETA IV CLASSIC is supplied without an FIA certification label, so it is not eligible for competition classes that require an FIA-homologated seat. It is built to BRIDE's safety standard compliant specification and carries the same shell rigidity and holding performance as the standard ZETA IV. Drivers who need FIA homologation should choose a ZETA IV variant that carries the label.

What is the difference between the ZETA IV CLASSIC and the standard ZETA IV?

The CLASSIC shares the standard ZETA IV shell shape, materials, rigidity, and dimensions, so holding power and rail fitment are unchanged. The differences are cosmetic and regulatory: small-diameter belt holes carried over from the ZETA III, gray double stitching on the cover, gold Classic headrest embroidery, a half-covered back, and no FIA certification label.

Which seat rails fit the BRIDE ZETA IV CLASSIC?

The BRIDE ZETA IV CLASSIC accepts BRIDE Super Seat Rail types FB, FG, FK, FO, FX, and IG. The correct type depends on the vehicle, the seating position, and whether a low or standard mounting height is wanted. Rails are vehicle-specific and sold separately, so confirm the type against the chassis before ordering.

How much does the ZETA IV CLASSIC weigh and how big is it?

The seat weighs approximately 7.5kg, or about 16.5lbs, with the silver FRP shell. It measures 460mm across the base, 560mm across the shoulder pads, 890mm tall, and 710mm deep. Those figures are identical to the standard ZETA IV, which is why rail and cockpit fitment carry over directly.

Is the ZETA IV CLASSIC suitable for street driving as well as track use?

Yes. The ZETA IV platform was developed to cover everything from public roads to hard sports driving on circuits. Molded urethane seat and thigh cushions, vertical back cushion slits, and the raised thigh profile keep the driver supported over long distances while still holding firmly under cornering load.

Description

BRIDE ZETA IV CLASSIC Bucket Seat in Black

The BRIDE ZETA IV CLASSIC puts the design language of the previous-generation ZETA III back onto BRIDE’s current standard-model platform without giving anything up in performance. Small-diameter belt holes and gray double stitching across the skin cover recreate the look that defined BRIDE’s earlier bucket seats, while the shell shape, material, and rigidity are pure ZETA IV. Black flame-retardant fabric covers a silver FRP shell, the headrest carries a gold Classic logo, and the half-covered seat back means no seat back protector is needed when the seat is fitted to the front of a vehicle that still has rear seats. It is built for owners of Japanese classics and modern sports cars who want period-correct presence with current-generation holding power, comfort, durability, and safety.

The ZETA Series

ZETA is the standard shape of the BRIDE full bucket seat, derived from ergonomics and the human skeleton, and it has been the best seller in the BRIDE full bucket range since 1990. The newly developed ZETA IV builds on the knowledge cultivated across the series and fits a wide spread of vehicle types without being tied to any single competition category. The new shell shape and the vertical slits in the back cushion improve the fit from the headrest through the back and shoulders, holding a correct driving position over long stints, while the raised thigh design resists the submarine phenomenon (the occupant sliding forward and down) under hard braking or impact. Shoulder width is reduced to 560mm and the LOWMAX System, previously reserved for selected full bucket and reclining models, brings seat center in line with steering center across a far broader list of vehicles.

The ZETA IV CLASSIC

The BRIDE ZETA IV CLASSIC revives the sharply drawn small-diameter belt holes of the previous ZETA III and adds gray double stitching to the surface cover, giving a modern full bucket seat a classical atmosphere that suits older and celebrated Japanese sports cars. Seat dimensions are identical to the standard ZETA IV, so rail compatibility and cockpit fit are unchanged. The shell is a silver FRP unit and the headrest carries gold Classic embroidery. Because the back of the seat is half-covered, the CLASSIC does not require the seat back protector that standard full bucket models need to meet safety standards when fitted in front of a rear seat. The CLASSIC is supplied without an FIA certification label.

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.
