The Sakura D3s stock plastic wheel hubs are poorly manufactured and tend to bend out of shape and even to break, causing massive wheel wobbling and chattering. These aluminium wheel hubs will most likely solve any wheel chattering issue.
they look gorgeous and are manufactured with high precision.
Only the screws to lock them onto the drive shafts dont take a lot of torque. I accidently broke one of the screws because i was applying too much torque to it, so be careful!
Otherwise its a great hop up, especially for the Sakura D3.
