WR02C Aftermarket Aluminium Front Lower Arm for Tamiya WRC2055 by GPM  [WRC2055]

WR02C aluminium lower arm overview

This aluminium front lower arm is a replacement component made for the Tamiya Honda City Turbo WR02C chassis and is supplied as a 1pr set under part number WRC2055. The section below outlines fitment advice, simple installation notes, and how the component is used when setting up small-scale touring suspension.

Fitment is specific to the WR02C designation included in the title. The arm typically replaces the original plastic lower arms while retaining existing hinge pins and mounting hardware where the factory geometry is preserved. Inspect pivot holes and fastener condition before fitting to keep steering behaviour predictable.

As part of suspension setup the front lower arm affects track width, scrub radius and lateral compliance. Swapping to aluminium lowers flex at the mounting points versus stock plastic parts, helping drivers get more consistent steering feedback across multiple runs.

When installing, do not over-torque pivot screws to avoid binding, and re-verify wheel alignment and suspension droop after the swap. Maintain the same mounting orientation and hardware length unless you intend a deliberate geometry change for tuning.

Use this aluminium lower arm when you want a firmer pivot point to aid consistent handling during setup sessions, and always perform a trial fit before finalising changes.
