The Tamiya Mini 4WD 9mm Aluminum Ball Race Rollers in pink are built to refine cornering balance and cut rolling resistance on your Mini 4WD. These ringless rollers suit racers wanting a lightweight upgrade that helps maintain speed through bends.
These aluminium ball race rollers deliver smoother lateral movement at the rail and help stabilise the car in corners. They fit common Tamiya Mini 4WD chassis types including MS, MA, AR, and VS, making them a flexible upgrade for many setups.
Fitting these rollers can noticeably change handling during faster sections and complex turns. The aluminium bodies keep added mass low while offering sufficient wear resistance for regular track sessions.
Beyond basic installation, these rollers combine well with performance tyres and speed-tuned motors to suit specific track profiles. Use them as part of a wider setup plan to balance grip and corner exit speed.
