Tamiya WR02C Aluminium Rear Lower Arm by GPM WRC2056  [WRC2056]

WR02C Rear lower arm (aluminium)

The GPM WRC2056 is an aftermarket aluminium rear lower arm made for Tamiya WR02C scale touring platforms, supplied as a 1pr set to replace the stock plastic arms on model Honda City Turbo WR02C bodies. It is designed as an RC-scale suspension part intended to offer a stiffer mounting point compared with original plastic components, preserving the chassis geometry expected on WR02C builds.

Installation focuses on direct substitution into the existing rear suspension pivot points without modifying the chassis; confirm fit against your WR02C knuckles and mounting hardware before final assembly. Use appropriate thread-lock and torque for small hex screws when securing the arm to prevent loosening under track use, and check clearance with the spur gear and suspension travel during the first test run.

As a tuning component, this aluminium arm changes flex characteristics that affect rear-end response and consistency during cornering for RC touring setups. Combine with matched shocks, springs, and anti-roll bar settings when tuning handling, and inspect all linkages after initial runs to verify wear patterns and ball bearing alignment.

For builders swapping to aluminium geometry points on a WR02C Honda City Turbo, the GPM WRC2056 provides a direct-fit rear lower arm option to adjust rear stiffness and tuning behavior within RC touring setups.
