Tamiya 15398 Double Roller Assembly 13-12mm JR - Corner Stability  [15398]

About the Tamiya 15398 Double Aluminum Rollers

The Tamiya 15398 Double Aluminum Rollers (13-12mm) are intended to improve the handling and steadiness of Mini 4WD cars. They make a sensible upgrade for racers aiming for cleaner cornering lines and consistent lap performance.

Design Concept and Performance

The unit uses two rollers, with a 12mm roller fitted above a 13mm roller to share contact forces around turns. This setup helps reduce lateral slip and supports smoother transition through corners. Aluminium offers a good balance of strength and low weight for race tuning.

Fitting Notes and Use Cases

• Suitable for Mini 4WD and Mini 4WD PRO chassis models.
• Assists with stability and cornering on typical Tamiya tracks.
• Easy to mount on standard chassis points, useful for quick setup changes.
