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

Aluminium front lower arm for WR02C tuning

This aluminium front lower arm is an RC-scale replacement designed for the Tamiya Honda City Turbo WR02C platform, supplied as a 1pr set with part number WRC2055. The notes below cover fitment checks, straightforward installation tips, and how the arm functions during small-scale touring car setup and tuning.

Compatibility is limited to the WR02C designation shown in the title. Installation usually replaces the factory plastic lower arms while keeping the original hinge pins and hardware when stock geometry is maintained. Inspect mating faces and pivot hardware for wear before assembly to preserve predictable steering and suspension behaviour.

From a setup perspective this front lower arm controls track width, scrub radius and lateral compliance. Replacing plastic arms with aluminium reduces flex at the mounting points compared with stock parts, helping to deliver more repeatable steering feedback during practice runs and setup changes.

When fitting, avoid over-tightening pivot screws to prevent binding, and verify wheel alignment and suspension droop after installation. Use the original mounting orientation and hardware length unless a deliberate geometry change is part of a setup adjustment.

Choose this aluminium front lower arm when you want a stiffer suspension pivot for more consistent handling during tuning sessions, and always check fit before committing to setup changes.
