Tamiya 15187 Lightweight Special Ratio Gear Set for Track Tuning  [15187]

Tamiya 15187 L.W. Special Ratio Gearing Overview

The Tamiya 15187 L.W. Special Ratio Gearing is a focused upgrade for Mini 4WD racers who want to refine their setup. Built to work with Super FM and Super TZ chassis, this lightweight gear set makes it easier to dial in gear ratios for better on-track performance without adding unnecessary weight.

Fitment and Operation

Made for seamless fit into Super FM and Super TZ platforms, the Tamiya 15187 gear set integrates cleanly with standard drivetrain layouts. Its special ratio options let racers tweak acceleration versus top speed, giving room to tune the car to suit different motors and wheel choices.

On-Track Benefits

Using a special ratio like this can sharpen acceleration out of corners and raise top speed on long straights, which is valuable on circuits with mixed sections. The lighter construction also aids responsiveness during quick direction changes and helps maintain consistent lap times.
