The 3Racing-labelled Tamiya Mini 4WD Double Aluminum Rollers in gold provide a stable platform for fine tuning handling characteristics. They are intended for racers who prioritise predictable response and easy setup changes during tuning sessions.
Manufactured to work with standard Mini 4WD chassis such as MS, MA, AR and VS, the 8-9mm size aims to balance roll resistance and agility. The gold surface aids quick visual checks during race day adjustments.
Deploying these rollers will typically reduce lateral instability in high-speed corners and help maintain line through technical track sections. Regular inspection of mounting points and rotation is recommended to ensure ongoing consistent performance.
Fitting is straightforward using standard Mini 4WD fasteners, enabling rapid iteration of roller positions. Tuners can experiment with placement to dial in entry and exit behaviour while monitoring wear to plan replacements.
