The Tamiya 95580 17mm Aluminum Rollers are a straightforward upgrade for Mini 4WD competitors looking for neater handling on twisty layouts. The shallow dish form strengthens the roller while allowing free spin, which is helpful for maintaining momentum in races.
Forged aluminium bodies house integrated 520 ball bearings to limit friction and preserve rotational energy. Red plastic rings give quick visual identification and act as a buffer against direct metal contact on barriers.
These rollers are suitable for both Mini 4WD and Mini 4WD PRO chassis variants. Certain body shells or alternative front/rear assemblies may need slight modification to ensure smooth operation and correct clearance.
Using 17mm rollers assists in maintaining steady contact with guide rails, improving cornering predictability and reducing lap time loss when paired with a considered setup and gearing choices.
