This aluminium roll spring holder is designed for the Yokomo R12 platform as an accessory for scale RC cars. It provides secure spring mounting points so adjustments to roll behaviour are predictable and repeatable.
The kit includes two sets, matching the usual part grouping on R12 touring car suspensions. Fit them to achieve consistent spring placement and a simple, low mass support for roll spring tuning at practice or competition.
Installation note: this component fits directly to the supported R12 chassis variants listed below, and its intended purpose is to relocate the roll spring to influence roll stiffness and transient response rather than to change the core suspension geometry.
