For Mini 4WD enthusiasts aiming for cleaner rolling and reduced drag, the Tamiya 15034 ball bearing set is a solid upgrade from standard plastic parts. These metal bearings reduce rolling resistance and help maintain steady wheel speed under load.
The Tamiya 15034 set works across many Mini 4WD chassis and is useful for both race and hobby projects. Reduced friction helps maintain speed consistency, which is particularly valuable on layouts with long fast sections.
