This aluminium front arm bulk serves as a scale replacement for the plastic front arm bulk on Tamiya CW-01 cars, including The Hornet and Grasshopper. It provides a more rigid mounting point in the front suspension assembly while preserving original fixing points and geometry.
The component functions as a structural stiffener, reducing flex where steering and suspension loads concentrate. That added stiffness alters steering feedback and suspension movement, so expect changes to handling and confirm wheel clearance and travel after fitting.
Installation follows standard CW-01 service practice: remove the existing front arm bulk from the bulkhead, carry over any pins or retainers, and fit the aluminium unit into the same positions. After fitting, check steering linkages, tie-rod alignment and the full range of suspension movement for any binding.
Use this part as one tool in setup adjustments to influence front-end stiffness. Since it modifies structural rigidity rather than spring characteristics, coordinate it with toe, camber and ride height adjustments to achieve the handling balance you want.
