Tamiya Mini 4WD Double Aluminum Rollers 12-13mm Red - 3RACING M4WD-34/RE Race Prep Set  [M4WD-34/RE]

Product Brief for Tamiya Mini 4WD Double Aluminum Rollers (12-13mm) - Red

The red double aluminium rollers from Tamiya offer a dependable upgrade to help your Mini 4WD car stay planted through corners. Designed to suit typical mounting formats, they are a common choice for racers tightening up handling.

Materials and Layout

These rollers use aluminium for a stiff, low-wear solution that resists bending. The stepped 12-13mm diameters give progressive contact with side rails, helping the car pivot smoothly while reducing the chance of catching or lifting during aggressive lines.

Compatibility Notes

Compatible across many Tamiya Mini 4WD models, these rollers match well with MS, MA, and AR chassis configurations. Their compact form helps keep overall weight down while adding stability where it matters.

Effect on Lap Times

When installed correctly, these rollers improve repeatability by keeping the car aligned on exits and entries, which can translate to tighter lap times on technical circuits. They are a practical tweak for racers seeking predictable responses from their setup.
