ARRIVING SOON

The Stier is a sleek, high-performance Mini 4WD racer built on Tamiya’s proven MA (Midship AERO) Chassis. Designed by renowned Mini 4WD designer Kota Nezu, the body takes inspiration from the powerful form of a bull, featuring muscular front guards, sharp aerodynamic lines, and an aggressive, low-slung profile.

The two-piece body combines a smoked centre section with contrasting coloured body panels, creating a layered appearance reminiscent of modern supercars. Builders can also remove the upper body panel for a unique open-top display style.
