Tamiya 15357 Mini 4WD PRO FRP Side Roller Extension - Track Control Kit  [15357]

Product summary for Tamiya 15357 side extension mount

The Tamiya 15357 Mini 4WD PRO FRP Side Extension Roller Mount is built to broaden supported Mini 4WD PRO MS chassis up to approximately 104mm. That extra track width helps reduce lateral roll and preserves momentum through sharper turns, a practical upgrade for racers looking to smooth lap consistency.

Fitment notes and installation tips

This FRP extension works with several chassis families, such as:

• 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 mostly bolt-on on compatible frames. When installing on Super-TZ or Super-1 variants, add the Item 15242 FRP Front Plate to ensure correct positioning. The part is versatile, allowing riders to alter roller layouts to suit different circuit types.

Track performance and upgrade paths

Increasing the chassis width enhances cornering stability and can lower the chance of losing speed in tight sequences. The mount accepts diverse roller choices and works well alongside tyre and damper upgrades for tailored handling responses.
