Summary of Tamiya Mini 4WD 9mm Rollers

The Tamiya Mini 4WD 9mm Aluminum Ball Race Rollers in pale blue are aimed at improving directional control and corner confidence for Mini 4WD models. These ringless units are designed for racers who need repeatable performance during meetups and club races.

Design and Compatibility Notes

Crafted for smooth contact with track guides, the 9mm aluminium rollers lower resistance at contact points and support stable driving lines. Their modest diameter balances roll support and minimal drag, while the blue finish helps when sorting parts at the bench.

Real World Racing Use

When installed, these rollers help drivers maintain a predictable race line over a range of course designs. Their lightweight construction avoids hampering acceleration, and they are broadly compatible with MS, MA, AR and VS chassis formats, offering straightforward upgrades for many builds.
