This rear brass weight is a dedicated tuning accessory made to mount on the rear H-arm assembly to alter unsprung mass at the rear axle. When mounted to a rigid aluminium H-arm base, the weight directs load onto the rear tyres independently of chassis pitch, reducing rear slide on corner entry and helping stabilise the rear end.
The kit includes two 10g brass weights that fasten to a base weight, giving stepped mass options without moving the chassis centre of mass. Treat this part as part of a wider setup approach — combine with tyre selection and suspension tweaks to refine rear bite and corner behaviour.
The Y2-008RW10 rear brass weight is aimed at drivers who want to tune rear unsprung mass and traction precisely. Mount on a compatible aluminium H-arm base and trial different tyres and suspension settings to achieve the handling goal.
