Brass weights to be attached to the rear arm. Combined with the aluminum Y2-008RAW rear H-arm, this is an optional part for RD2.0/SD2.0 that can systematically increase rear traction. By mounting weights on the rigid aluminum H-arms, it is possible to increase the unsprung weight that is directly applied to the rear tires, effectively increasing the traction of the tires. Unlike increasing the weight of the chassis, the load is applied regardless of the pitching motion, so the slide fits well and the stability can be maintained even when entering a corner. It contains two 10g weights to be attached on the base weight.
