Tamiya Honda City Turbo WR02C Aluminium Front Lower Arm by GPM WRC2055  [WRC2055]

Front lower arm for WR02C

This aluminium front lower arm is an RC-scale replacement part designed for the Tamiya Honda City Turbo WR02C platform, supplied as a 1pr set under GPM part number WRC2055. The text below focuses on fitment considerations, basic installation notes, and how the part is used during setup and tuning of small-scale touring car suspension.

Compatibility is specific to the WR02C designation listed in the product name. Installation typically replaces the original plastic lower arms, retaining existing hinge pins and hardware where the stock geometry is unchanged. Inspect mating points and pivot hardware for wear before assembly to maintain predictable steering and suspension response.

In tuning context the front lower arm is a suspension location item that influences track width, scrub radius, and lateral compliance. Swapping to an aluminium arm is used to reduce flex at the mounting points relative to stock plastic parts, which can produce more consistent steering feedback during setup iterations on track or practice runs.

When fitting, avoid over-tightening pivot screws to prevent binding, and verify wheel alignment and droop after installation. Use the same mounting orientation and hardware length as the original part unless a different geometry is specifically required by a setup change.

Use this aluminium front lower arm when a firmer suspension pivot is desired for consistent handling during tuning sessions, and always verify fit before committing to setup changes.
