This 3RACING Aluminium Ball Differential System Ver. 2 is engineered for competitive tuning on the Tamiya M03M platform. It provides a more controlled torque distribution and improves corner exit predictability when set up with appropriate preload and lubrication.
By offering a refined differential action, this unit helps drivers tune understeer and oversteer characteristics more precisely. Adjusting preload and ball contact can deliver measurable improvements in lap consistency.
Installation aligns with standard Tamiya M03M drivetrain points. For race setups, test a range of preload settings and diff greases to match surface grip and driving style; document each change to evaluate handling differences.
