Tamiya 15398 JR Double Aluminium Double Rollers 13-12mm - Track Ready  [15398]

Introduction to Tamiya 15398 Double Aluminum Rollers

The Tamiya 15398 Double Aluminum Rollers (13-12mm) aim to increase cornering stability for Mini 4WD models. They are a practical component for modders looking to tighten corner performance without adding unnecessary mass.

How the Double Roller Works

The set places a 12mm roller above a 13mm roller to create a two-point support that shares loads through bends. That layout reduces yaw during high-speed sections and helps the car track truer around corners. Aluminium construction balances robustness with lightweight characteristics desirable in competitive tuning.

Compatibility and Practical Tips

• Compatible across Mini 4WD and Mini 4WD PRO chassis systems.
• Improves handling and cornering consistency on standard circuits.
• Simple installation makes it useful for quick changes between heats or practice sessions.
