Yokomo Y2-008RAW Aluminum Rear H Arm (For weight loading/Short) 橫崛 Yokomo DP-GRA90W  [Y2-008RAW]

　This is an optional part for RD2.0/SD2.0 that combines an aluminum rear H arm and a brass weight to systematically increase rear traction.
By mounting a separately sold weight on the highly rigid aluminum H-arm, it is possible to increase the unsprung weight that is directly applied to the rear tire, effectively increasing tire traction. Unlike increasing the weight of the chassis, the load is applied regardless of the pitching action, so the slide is well contained even when entering a corner, and a sense of stability can be maintained. By adding 5g or 10g weights to the base 20g weight, you can control the amount of load applied.
