Tamiya 94603 Aluminium Side Extension Roller Mount - Mini 4WD Stability Kit  [94603]

Tamiya 94603 Aluminium Side Extension Roller Mount - Chassis Widening Upgrade

The Tamiya 94603 Aluminium Side Extension Roller Mount is a practical aluminium upgrade for Mini 4WD fans aiming to improve handling and consistency on the track. It increases chassis width to roughly 104mm for better lateral stability while keeping weight low thanks to its aluminium construction. The extension fits multiple Mini 4WD chassis, making it a handy addition for racers who swap between cars.

Fitment and How to Install

This roller mount installs directly on Mini 4WD PRO, Mini 4WD VS, Super X, and Super TZ-X chassis without modification. If you run Super-TZ or Super1 layouts, you will need ITEM 15242 to complete the installation. That adaptability makes the Tamiya 94603 suitable for crews who race different chassis types.

On-Track Advantages

Widening the chassis improves stability through corners and helps maintain speed when changing direction. The added width can reduce roll and make car setup more predictable during timed laps and organised races.
