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

Front lower arm - WR02C fit and function

This aluminium front lower arm is a scale replacement made for the Tamiya Honda City Turbo WR02C chassis, supplied as a 1pr set bearing the part number WRC2055. The following copy focuses on fitment guidance, basic assembly notes, and how the arm is used when dialing in touring car suspension settings.

Compatibility is specific to WR02C as stated in the product name. Installation normally swaps out the original plastic lower arms while keeping the stock hinge pins and fasteners when geometry is unchanged. Check mating surfaces and pivot hardware for wear prior to installation to ensure consistent steering response.

In tuning terms the front lower arm sets lateral stiffness, scrub radius and track position. Upgrading to an aluminium arm reduces movement at the mount points relative to plastic, which helps produce steadier steering feel during setup sessions and repeats on track.

During fitting take care not to overtighten pivot screws which can cause binding, and re-check wheel alignment and suspension travel once installed. Keep mounting orientation and hardware lengths the same unless a specific geometry change is required.

Fit this aluminium lower arm when you need reduced pivot compliance for repeatable handling during tuning, and always trial-fit before locking in a new setup.
