Tamiya 18660 - 1/32 Jr Stier MA Chassis Mini 4WD Kit, compact racer  [18660]

Overview of the Tamiya 18660 Jr Stier

The Tamiya 18660 Jr Stier brings a sporty Mini 4WD silhouette to club racing and weekend builds. Its two-seater hyper car cues and distinct U-shaped front give the model a bold track presence without sacrificing a compact footprint.

Styling and body details

The body is moulded in silver ABS plastic for a durable finish. Separate rear fender pieces add realistic depth, while metallic stickers let you personalise the look. Its compact footprint of 156mm long, 97mm wide and 37mm tall makes it ideal for tight Mini 4WD circuits.

MA chassis balance and parts

The MA chassis features the central double-shaft motor layout for even weight distribution and predictable handling. Produced in black ABS, the chassis includes low friction A parts to help reduce drivetrain losses and improve lap times.

Tuning and upgrade options

With a 3.5:1 gear ratio the Jr Stier is set up for quick acceleration. Builders can fit higher performance motors, experiment with tyre compounds, and swap precision gears to refine speed and cornering on standard Mini 4WD tracks. The low-profile tyres and five-spoke wheels are aimed at grip and straight-line roll.

The Tamiya 18660 Jr Stier blends a stylised hyper car body with the adaptable MA chassis, offering a straightforward build and solid base for performance tweaks.
