Tamiya 18083 JR Shirokumakko - Polar Themed Super-II Mini 4WD Kit  [18083]

What the JR Shirokumakko 18083 offers

The Tamiya 18083 JR Shirokumakko mixes a quirky polar bear theme with a race-capable chassis. Built on the Super-II platform, this Mini 4WD kit is aimed at hobbyists who enjoy both customization and track performance.

Design and body notes

Inspired by the Terra Conqueror open-top look, the JR Shirokumakko body delivers an aerodynamic profile and a fun driver figure. Moulded in ABS, the shell resists impacts while staying light enough for speed-focused setups.

Details on the Super-II chassis

The Super-II chassis in pale blue provides a sturdy base for tuning. Its common mounting points make it straightforward to add upgrades or reinforce areas affected by frequent racing wear.

Upgrade suggestions for racers

Consider these upgrades to boost lap times:

• Motors: Uses the standard 130 single-shaft range so you can choose motors tailored to your racing style.
• Tires and Wheels: Supplied gold-plated wheels and blue tyres look good and can be swapped for lower profile or grippier compounds.
• Gears: Testing different gear sets helps find the right compromise between acceleration and top end speed.
• Dampers: Adding dampers reduces bouncing and helps maintain traction over uneven sections.

Assembly tips for a tidy build

The snap-fit design keeps assembly clean and quick, perfect for weekend projects. Experienced builders can still add screws or braces to increase torsional rigidity.

With its distinctive look and upgrade-friendly Super-II chassis, the JR Shirokumakko is a fun addition for anyone into competitive Mini 4WD building.
