The LOWMAX system for the ultimate low position and a backrest shape with a characteristic round shoulders line were adopted.

ZIEG IV is a full bucket seat that has been elaborated to pursue the high safety and the hold performance based on various racing experiences and feedback from professional drivers. The entire shell has a deep hold shape with the round backrest line for wrapping the driver deeper. Even in situations where high-speed cornering or high driving G is applied, the driver is firmly held for reliable driving operations. By the BRIDE patented LOWMAX system and the egg-shaped backrest provide a low seat position, ensuring an ideal eye point and driving position.

The shell material can be selected from two types: FRP silver shell and Super aramid black shell, and the color variation can be selected from three types: Gradation logo, Black and Red.

ZIEG IV is a FIA approved model.

New shell design in pursuit of functionality and utility

The shape fits from headrest to back, shoulders, especially shoulder bone. The vertical stitching of the back cushion follows naturally the spine. The tough PVC leather is used for the sides which is often rubbed when getting on and off. It has become a new design to be particular about the details.


FIA approved and Conformity to the safety standard

ZIEG IV conforms to the safety standards of the Japanese Road Transport Vehicle Act (for automobile inspection). In addition, it has also acquired the “FIA8855-1999” standard established by the FIA (International Automobile Federation), so it can be used in international formality races and competitions. It has a high level of safety by having the design and quality for passing to the more severe test.

ZIEG IV Dimensions:


Low position essential for circuit and sports driving

ZIEG IV has installed the LOWMAX system which is a patented technology of BRIDE, Furthermore, the backrest has a round shape, so the head position (eye point) can be lowered. This seat is ideal for more competitive scenes such as circuit driving.


Advanced material and Manufacturing method

By adding more high-performance materials to the FRP shells (glass fiber and aramid fiber) that have been used so far, the shell rigidity has been increased by 15%. The seat cushion and thigh cushion, which are in close contact with the body, have newly adopted molded urethane to improve comfort and durability for long driving.


Shell design and hold performance considering safety

The new shell shape and vertical slits in the back cushion improve the fit from the headrest to the back, shoulders, and can keep the appropriate driving position for a long time without difficulty. The shape design with the thigh lifted prevents the submarine phenomenon (a phenomenon in which the occupant sinks in the forward downward direction) during hard braking or collision accident.


Adopted large seat belt holes

The large seat belt hole which was previously installed in the ZETA III PLUS and XERO series has been newly adopted in the ZIEG IV too. This makes it possible to match a wide range of wearing conditions for racing harnesses and FHR systems (head and neck protection devices), which occur due to differences in driver height and sitting height.
