Tamiya 15525 Dual Low-Friction Rollers with Rubber Rings - Red and Blue 13/12mm  [15525]

Roller Upgrade Overview

The Tamiya 15525 Low Friction Plastic Double Rollers with Rubber Rings are a straightforward upgrade for Mini 4WD racers seeking improved corner control. These rollers use a two-step diameter layout, 13mm on the lower roller and 12mm on the upper roller, presented in red and blue. Molded from low-friction POM plastic, the smaller top roller includes a fitted rubber ring to smooth rotation and reduce bouncing.

Handling and Fit Notes

Designed to stabilise Mini 4WD handling, the larger bottom roller supports line keeping while the smaller top roller, with its rubber ring, cushions contact with the walls. They fit most Mini 4WD and Mini 4WD PRO setups, though some car bodies may need trimming or alternate mounting points to accommodate the dual roller profile.

Race Day Benefits

On tight tracks these Tamiya 15525 rollers help maintain speed through corners by cutting rolling friction and limiting sudden deviations. Installation is user friendly, making them suitable for newcomers who want a practical upgrade without complex tuning. The rubber rings also help maintain consistent wheel contact during high-speed transitions.
