Which seat rails fit the ZIEG IV CLASSIC Bucket Seat?

The ZIEG 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.

Is this seat FIA approved?

No. It is supplied without an FIA certification label, so it is not eligible for competition classes that require an FIA-homologated seat. The shell shape, rigidity and holding performance are the same as the standard ZIEG IV. Drivers who need homologation should choose a variant that carries the label.

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

They share the 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 ZIEG III, gray double stitching on the cover, a half-covered seat back, and no FIA certification label.

Does it need a seat back protector?

No. Standard full bucket seats need a protector, sold separately, to meet safety standards when fitted to the front of a vehicle that still has rear seats. The upper back shell is half-covered from the factory, so the protector is not needed here.

How much does it weigh and how big is it?

The seat weighs 7.7kg, about 17.0lbs, with the silver FRP shell. It measures 460mm across the base, 560mm across the shoulder pads, 900mm tall and 670mm deep. Those figures are identical to the standard ZIEG IV, which is why rail and cockpit fitment carry over directly.

How does it compare with the ZETA IV CLASSIC?

Both carry the same classical treatment, but the shells underneath differ. ZETA is the standard BRIDE full bucket shape. ZIEG is the deep hold shape, with a rounded backrest that wraps further around the shoulders for harder cornering loads. Drivers who want the firmer wraparound hold should take the ZIEG.

Description

BRIDE ZIEG IV CLASSIC Bucket Seat in Black

The BRIDE ZIEG IV CLASSIC Bucket Seat puts the styling of the previous-generation ZIEG III back onto BRIDE’s current deep hold platform without touching the shell underneath. Small-diameter belt holes and gray double stitching across the cover recreate the look of BRIDE’s earlier bucket seats, while the shape, materials and rigidity stay pure ZIEG IV. Black flame-retardant fabric covers a silver FRP shell at 7.7kg, and the half-covered seat back means no seat back protector is needed when the seat goes in front of a rear bench. It suits owners of Japanese classics and modern sports cars who want period-correct presence with the wraparound hold the ZIEG shell is built for.

The ZIEG Series

ZIEG is the deep hold shape in the BRIDE full bucket range, developed out of racing experience and direct feedback from professional drivers. The rounded backrest line wraps the driver from the hips through the shoulders and holds them in place under sustained lateral G, without the pressure points that come from a seat that grips by being narrow. The patented LOWMAX System works with the egg-shaped backrest to set the seat lower than a conventional full bucket allows, putting the eye point and driving posture where car control wants them, which matters most in cars where headroom is tight. The FRP shell carries glass fiber and aramid fiber for 15% more rigidity than the previous construction, and molded urethane is used for the seat and thigh cushions that take the driver weight directly.

The CLASSIC

This is the classical treatment of the deep hold shell: the sharply drawn small-diameter belt holes of the ZIEG III return, and gray double stitching is added to the cover, giving a current full bucket a look that suits older and celebrated Japanese sports cars. Seat dimensions are identical to the standard ZIEG IV, so rail fitment and cockpit clearance carry over unchanged. The shell is a silver FRP unit finished in black flame-retardant fabric. Because the upper back shell is half-covered from the factory, no seat back protector is needed when the seat is fitted in front of a rear seat.

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.
