Tamiya 15345 DR 11mm Ball Bearings for Mini 4WD (2 pcs.) - precision tuning pair  [15345]

What these bearings deliver

The Tamiya 15345 DR 11mm Ball Bearings are a pair of precision parts that reduce friction in Mini 4WD assemblies. They help wheels rotate with less resistance, which improves roll and responsiveness during sprints and lane changes. Ideal for builders fine tuning a racer or weekend project car.

Compatibility with common chassis

Designed to fit a broad selection of Mini 4WD configurations, these 11mm bearings pair well with many Tamiya chassis types. Builders using MS and MA platforms will find them particularly useful for lowering drive resistance on both stock and mildly upgraded setups.

Practical effects on racing setups

Adding ball bearings smooths wheel motion and reduces stop-start losses at the axles, leading to steadier acceleration and improved top speed on straight sections. For anyone focused on lap-to-lap consistency, they are a worthwhile tuning item.
