The Tamiya 95160 Aluminum Ball-Race Roller Set J-Cup 2023 is aimed at Mini 4WD hobbyists wanting smoother roller action and steadier lap times. These compact 19mm rollers use ball-race bearings to keep rotation efficient and predictable.
Crafted from aluminium to balance durability and weight, the rollers sport a blue anodised surface with Japan Cup and Tamiya logo prints for a race-ready look. Be cautious with cleaners around the printed areas to prevent wear.
Rubber rings fitted to each roller help absorb contact shocks from track walls, which improves stability during fast runs. They fit many Mini 4WD and Mini 4WD PRO cars, though certain chassis or body setups may require small adjustments. All necessary small parts for mounting are included in the kit.
