The Tamiya 95580 17mm Aluminum Rollers are a sensible upgrade for Mini 4WD fans wanting cleaner lines through corners. The dish-shaped profile increases strength while still allowing free spin, helping cars hold pace on challenging layouts.
These rollers are crafted from aluminium and fitted with 520 ball bearings for low rolling resistance. The red plastic rings help protect the metal surface and make each roller easy to identify during pit checks or tuning sessions.
These rollers are compatible with Mini 4WD and Mini 4WD PRO chassis designs and can be used with a variety of setups. Some body shells or custom bumpers may need slight trimming or additional spacers to clear the roller edges.
Installing 17mm rollers provides a steadier contact point against guide rails and track walls, which tends to reduce speed loss when negotiating corners. They are a common choice for drivers refining handling without major chassis changes.
