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.
