Tamiya Mini 4WD Double Aluminum Rollers (8-9mm) - Light Blue Technical Summary

The Tamiya Mini 4WD Double Aluminum Rollers in light blue are a compact upgrade aimed at racers refining chassis behaviour. They provide controlled lateral support to improve repeatability through complex sections while remaining easy to install.

Engineering and Fitment Notes

These double aluminium rollers are intended to reduce contact drag and constrain lateral play at the wheel plane. The 8-9mm dimensional range permits small incremental changes in clearance, useful for tuning ride height and edge clearance on MS, MA and AR chassis families.

Performance in Racing Scenarios

When deployed on technical circuits, these rollers stabilise the vehicle during cornering phases, reducing abrupt lateral shifts that interrupt momentum. Their predictable behaviour helps when optimising line consistency across repeated laps.

Tuning Workflow

For competitive setups, adjust roller offset and tilt in small steps and record lap times and behaviour. Combining these rollers with front and rear geometry changes allows targeted tradeoffs between corner entry stability and exit acceleration.
