Tamiya WR02C Rear Knuckle Arm Aluminium Performance Upgrade - WRC2022 by GPM  [WRC2022]

Stiff aluminium rear knuckle for WR02C

This aluminium rear knuckle arm is offered as an aftermarket replacement for the Tamiya Honda City Turbo WR02C. Supplied as a 1pr set, it is intended to provide a stiffer, longer-lasting mounting point for the rear wheel spindle than typical stock plastic pieces.

Fitting is a direct replacement operation: remove the stock rear knuckle, transfer bearings or inserts as required, and fit the aluminium arm into the existing mounting positions. Keep original fasteners where serviceable to preserve alignment and geometry.

From a setup viewpoint, aluminium knuckles raise structural stiffness at the rear and change steering response. Drivers looking to tighten rear-end behaviour or reduce flex will find this a useful upgrade, but should plan to reassess toe and damping after installation to achieve the desired handling balance.

A practical aftermarket upgrade for model builders seeking increased rear rigidity and more defined steering feedback on the WR02C Honda City Turbo chassis; installs using the original mounting points for a clean swap.
