Tamiya WR02C Aluminium Rear Knuckle Arm for Honda City Turbo - WRC2022 by GPM  [WRC2022]

Machined aluminium rear knuckle for WR02C

This machined aluminium rear knuckle arm is an aftermarket replacement for the Tamiya Honda City Turbo WR02C platform. Supplied as a 1pr set, the component gives a noticeably tougher, less flexible mounting point for the rear wheel spindle compared with common stock plastic parts.

Fitment follows a like-for-like swap: remove the stock knuckle, transfer any bearings or inserts as needed, and secure the aluminium arm in the original mounting locations. Where possible reuse original fasteners to maintain alignment and correct geometry, replacing only damaged hardware.

As a tuning item, moving to an aluminium rear knuckle changes chassis stiffness and rear steering feel. Drivers chasing crisper rear response or reduced flex under heavy corner loads will often pair this arm with revised suspension arms or altered shock settings. Because stiffness changes rather than geometry, expect to check toe and dampening after installation to dial in handling.

This aluminium rear knuckle arm is a direct aftermarket upgrade for modelers wanting firmer rear-end mounting and clearer steering feedback on the WR02C Honda City Turbo chassis; installation uses the original mounting points for a straightforward swap.
