Tamiya 15418 JR Double Aluminum Rollers with Rubber Rings (13mm/12mm) - Precision Cornering  [15418]

Introduction to Tamiya 15418 JR Double Aluminum Rollers

The Tamiya 15418 JR Double Aluminum Rollers are a precision-focused upgrade for Mini 4WD racers. The combination of 13mm and 12mm rollers with fitted rubber rings helps maintain consistent wall contact and reduces unplanned slips in corners.

Engineering and performance

These aluminum rollers are engineered for durability and minimal flex under load. The rubber rings on the smaller rollers provide progressive resistance that smooths impacts and helps the car exit corners more predictably.

Suitable chassis and setup guidance

Compatible with both Mini 4WD PRO and standard Mini 4WD models, the rollers are straightforward to install. Consider ride height and bumper position when integrating them to preserve correct line geometry.

Effect on lap times

By cutting down lateral movement at the contact point, the Tamiya 15418 rollers allow for more aggressive corner entries while keeping rebound under control, which can translate to improved consistency across laps.
