This aluminium roll spring holder is made to work with the Yokomo R12 platform as a scale RC upgrade. It secures roll springs and establishes predictable mounting positions so tuning changes are straightforward to repeat.
Two sets are supplied to mirror the paired configuration used on R12 touring suspensions. Use these holders when you want reliable spring location and a lightweight support that aids consistent roll spring adjustment during setup sessions.
Installation note: the item is intended for direct fitting to the supported R12 chassis variants listed below, and its tuning role is to adjust roll spring placement and thereby influence roll stiffness and transient response rather than to modify primary suspension geometry.
