The Tamiya Mini 4WD pink double aluminium rollers are designed for modelers wanting more dependable corner entry and exit. They work well as an upgrade part for racers refining handling on twisty layouts.
The double diameter layout, sized 16-17mm, helps maintain steady rail contact through corners and transitions. These aluminium rollers suit a broad range of Mini 4WD platforms and reduce inconsistent bounce compared with some softer materials.
Aluminium offers a durable option that keeps mass low, aiding acceleration while providing a firmer surface for corner guidance. Replacing stock plastic rollers with aluminium can enhance predictability in lap-to-lap performance.
Installation requires basic tools and uses the included fixings to secure the rollers. Check clearances after fitting to avoid rubbing and confirm free rotation under load.
