Mini 4WD competitors will find the Tamiya 95382 Lightweight 13mm Aluminium Ball-Race Rollers a practical tuning part for improved track behaviour. Manufactured to lower wall contact drag, these rollers house 520 ball bearings to keep rotation smooth and dependable during heats. They can be fitted to either the front or rear to help dial in your car's balance.
The key advantage is weight saving. The barrels have been re-drilled to cut roughly 30% of the weight compared with conventional rollers, which helps with acceleration and nimble handling. The vibrant blue finish gives your model a neat, customised appearance.
