Technical Summary of 12-13mm Double Rollers

The Tamiya Mini 4WD Double Aluminum Rollers, 12-13mm in pink, are engineered to support precise rail interaction and reduced lateral deflection during high speed cornering. They are intended for competitive setups where consistent contact and minimal deviation matter.

Chassis Compatibility and Installation Notes

These rollers are compatible with MS, MA, AR and VS chassis types. For optimal performance, mount using correct post types, set precise spacer stacks to align roller face with the guide rail, and verify axial play is within acceptable limits to avoid wobble under load.

Tuning Impact and Race Setup Guidance

The double roller configuration helps maintain a stable line through transitions and improves exit predictability. Combine these rollers with measured tyre selection and balanced weight distribution to maximise lap time gains in competitive environments.

What spacer stack works best with these rollers?

Start with a minimal spacer stack to centre the roller face on the guide rail, then add increments to prevent rubbing. Verify under load as suspension and chassis flex can change clearances.

How do these rollers influence tuning choices?

They encourage a setup that favours controlled cornering; expect to fine tune gearing and tyre compound to complement the improved rail stability.

Are there limitations to aluminium rollers?

Aluminium offers strength and wear resistance but can transmit more shock to mounting points than polymer rollers, so inspect posts and screws regularly and consider vibration dampening if needed.
