Rear hub carrier for YD-2 series. The rear hub carrier used in the front and rear brake disc/caliper specification sets allow dummy break calipers to be installed. The upper arm mounting position is increased, and the width of the roll center and ground camber changes can be set to actively utilize the roll. In particular, on road surfaces with low grip such as P tiles, the upper arm mounting position is elevated to maintain the ground area when the chassis is rolled, ensuring a stable grip in the side for an aggressive ride.
