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

Overview of JR Shirokumakko by Tamiya 18083

The Tamiya 18083 JR Shirokumakko places a whimsical polar bear theme into a competition-ready Mini 4WD package. Built on the Super-II chassis, it is ideal for hobbyists who want a blend of fun design and practical tuning potential.

Exterior styling and graphics

The open-top body echoes the Terra Conqueror profile with streamlined panels for reduced drag. A miniature polar bear driver adds charm, and the ABS moulding keeps the shell light yet resilient for repeated track use.

Super-II chassis features and setup

The light blue Super-II chassis is favoured for its modification options and robust build. Its layout supports common performance parts, making it easy to test different setups on carpet or plastic race circuits.

Performance upgrades to consider

Several common upgrades will lift performance:

• Motors: Compatible with the standard 130 single-shaft motor family, so you can pick motors to suit sprint or endurance races.
• Tires and Wheels: Factory gold-plated wheels and blue tyres can be changed to low profile or foam options for reduced rolling loss.
• Gears: Swapping gear ratios lets you tune acceleration against top speed for each event.
• Dampers and stabilisers: Fit dampers to control bounce and keep stability through chicanes and banked curves.

Building tips and tricks

The snap-fit construction keeps assembly straightforward while allowing room for riders to add reinforcements or lightweight mods to improve durability and performance.

Tamiya JR Shirokumakko is a stylish Mini 4WD that blends collectable appeal with sensible upgrade routes thanks to the Super-II chassis.
