Track-ready Tamiya 15345 DR 11mm Ball Bearings for Mini 4WD (2 pcs.)  [15345]

Performance overview for racers

The Tamiya 15345 DR 11mm Ball Bearings come as a two piece set engineered to cut friction in Mini 4WD drivetrains. These precision bearings let wheels spin more freely, helping racers refine acceleration and maintain higher speeds on short tracks. They are a simple upgrade for anyone tuning a competing Mini 4WD.

Fitment and chassis notes

These 11mm bearings are made to suit a wide range of Mini 4WD chassis and installation points. They work well in many Tamiya setups, including common MS and MA chassis layouts, and can be used in both stock and mildly modified configurations to reduce rotational drag.

On-track benefits and handling

Installing ball bearings reduces mechanical resistance at the wheel and axle interfaces, which translates into smoother rotations and more consistent speed through corners. For club racers and hobbyists focused on lap consistency, these bearings are a straightforward way to improve performance without complex mods.
