WR02C Touring Rear Lower Arm Aluminium Replacement - WRC2056 by GPM  [WRC2056]

Aftermarket aluminium rear lower arm for WR02C

The WRC2056 is an aluminium rear lower arm made as an aftermarket replacement for the Tamiya WR02C touring chassis, supplied as a 1pr set to replace the stock plastic arms on the Honda City Turbo WR02C bodyshell. The part is intended to increase rigidity at the rear while retaining the chassis geometry expected from WR02C builds.

Designed for direct substitution at factory rear pivot points, the arm normally installs without altering the chassis. Confirm knuckle clearance and fastener fit before fully torquing components. Use thread-lock on metal-to-metal screws and observe proper torque for small hex heads to reduce the risk of fastener loosening under regular running.

As a tuning upgrade, the aluminium lower arm will change rear flex and handling behaviour, often delivering more consistent corner exit. Pair with appropriate shock valving and anti-roll bar adjustments and inspect linkage alignment and bearing fit after initial track usage.

The WRC2056 gives WR02C Honda City Turbo owners a direct-fit aluminium rear lower arm for tuning rear stiffness and improving repeatability in touring car setups.
