Tamiya 18660 - 1/32 Jr Stier MA Chassis Mini 4WD Kit, off-road favourite  [18660]

About the Tamiya 18660 Jr Stier kit

The Tamiya 18660 Jr Stier brings hyper car aesthetics to the Mini 4WD format, with a bold U-shaped nose that catches the eye and a scaled design built for close racing.

Exterior styling and finish

Built from silver ABS plastic, the body offers toughness and shine. Separate rear fender sections add depth and the metallic sticker sheet makes custom liveries straightforward. Measuring 156mm by 97mm by 37mm, the model fits well on standard circuits.

Key points of the MA chassis

The MA chassis adopts a central double-shaft motor position that helps equalise weight distribution for predictable cornering. The black ABS chassis incorporates low friction A parts to keep drivetrain resistance down during competition.

Performance tuning notes

The 3.5:1 gear ratio is tuned for quick acceleration out of corners. Builders can upgrade to performance motors, try different tyre choices and adjust gearing to match track demands. The supplied low-profile tyres and five-spoke wheels are a solid starting point for speed and grip balance.

Tamiya 18660 Jr Stier combines distinctive styling with the MA chassis versatility, making it a practical platform for racers wanting a straightforward upgrade path.
