BRIDE Full Bucket Seat ROMAX The ZETA IV is a model in the ZETA series. With a shell design that fits the Japanese physique and skeletal structure, it's BRIDE's flagship model, designed for various situations, from public roads to hard sports driving. Based on BRIDE's accumulated seat-making technology and know-how, it utilizes various materials to achieve both light weight and high rigidity. It's a full bucket seat that surpasses previous models in terms of hold, usability, durability, and stability. The ZETA IV is a FIA-approved model. Includes Mazda Speed Axela seat rails. The seat position was too low, so the height has been adjusted DIY style. Please remove it when not needed. I think the condition is relatively good.
