The Yokomo Y2-008RAW Aluminium Rear H Arm is a purpose part for RD2.0 and SD2.0 chassis that improves rear tyre contact through targeted mass placement. The high-stiffness aluminium piece combined with an optional brass weight increases unsprung mass at the rear wheels to help tyres bite without upsetting the chassis pitching behaviour.
Rather than bolting on ballast to the chassis, this H arm puts weight where it directly affects the tyres. Fit the standard 20g weight and add 5g or 10g increments to tailor traction for carpet, tarmac or mixed surfaces and keep handling consistent session to session.
