Tamiya 94603 Aluminium Side Extension Roller Mount Mini 4WD Upgrade  [94603]

Tamiya 94603 Aluminium Side Extension Roller Mount - Improve Cornering

The Tamiya 94603 Aluminium Side Extension Roller Mount is a straightforward upgrade for Mini 4WD enthusiasts who want more stable handling. Expanding the chassis to around 104mm broadens the car's stance, helping it negotiate corners with better composure while aluminium construction preserves strength and lightness. This extension works across a number of Mini 4WD chassis types.

Fitment Notes and Installation Guidance

This roller mount is engineered to fit the Mini 4WD PRO, Mini 4WD VS, Super X, and Super TZ-X chassis without changes. If you intend to fit it to Super-TZ or Super1 chassis, ITEM 15242 is required to complete the installation. That makes the Tamiya 94603 a practical choice for racers running varied chassis.

Track-Level Benefits

Widening the chassis improves lateral stability and helps keep the car predictable during quick directional changes. The result is improved control through technical sections and greater confidence at higher speeds.
