Tamiya 18660 - 1/32 Jr Stier MA Chassis Mini 4WD Kit, tuned for handling  [18660]

Introducing the Tamiya 18660 Jr Stier model

The Tamiya 18660 Jr Stier injects hyper car styling into the Mini 4WD lineup. Its pronounced U-shaped front evokes a bull-like motif while keeping a compact scale that makes it nimble on technical layouts.

Bodywork and build materials

The shell is made from silver ABS plastic for impact resistance and a tidy finish. Separate rear guards add realism and the metallic decal set helps you personalise the car. Its dimensions are 156mm long, 97mm wide and 37mm high, giving a low centre of gravity for quick direction changes.

MA chassis layout and benefits

The MA chassis uses a central double-shaft motor position to centralise mass and produce stable behaviour. Constructed from black ABS, the chassis includes low friction A parts designed to reduce drivetrain drag during competition runs.

Setup and upgrade path

Equipped with a 3.5:1 gear ratio, the kit is ready for acceleration-first setups. Racers often try higher torque motors, alternative tyres and finer gear choices to suit slick tracks. The low-profile tyres and 5-spoke wheels balance grip and rolling efficiency.

Tamiya 18660 Jr Stier pairs a distinctive hyper car body with the versatile MA chassis, offering clear upgrade routes for racers focused on handling and lap consistency.
