This upgrade kit targets Mini 4WD owners focused on lap time consistency and handling. The Tamiya 15381 JR PRO Low Friction Roller Set uses engineered polyacetal rollers to lower bearing resistance while keeping component weight down.
Compatible with all Mini 4WD platforms, this set helps sharpen cornering and reduce speed loss through turns. Brass roller receivers and the included screws, nuts and washers make installation straightforward and robust for competitive use.
