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

Frequently Asked Questions

• 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.
