Tamiya 15357 FRP Side Roller Extension for Mini 4WD PRO - Stability Pack  [15357]

Brief on the Tamiya 15357 FRP side extension

The Tamiya 15357 Mini 4WD PRO FRP Side Extension Roller Mount lets you extend suitable Mini 4WD PRO MS chassis to near 104mm track width. That broader stance helps control lateral movement during fast cornering and aids consistent lap timing on trickier track layouts.

Which chassis fit and how to install

The extension is compatible with a variety of chassis types, including:

• Direct Use: Mini 4WD PRO MS chassis, Mini 4WD VS, Super X, Super TZ-X
• With Item 15242 FRP Front Plate: Super-TZ, Super-1

Installation is straightforward on supported chassis. Use the Item 15242 FRP Front Plate when adapting the mount to Super-TZ or Super-1 frames. The part offers room for setup changes so racers can tune roller position and tyre choice to match circuit demands.

Handling improvements and tuning ideas

By widening the chassis, the mount reduces mid-corner slide and helps maintain drive through bends. It is compatible with different roller setups and pairs well with tyre and damper tweaks for finer handling control.
