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

Aluminium rear knuckle arm for WR02C

This aluminium rear knuckle arm is an aftermarket replacement part produced by GPM for the Tamiya Honda City Turbo WR02C platform. Supplied as a 1pr set, the component focuses on providing a durable, stiffer mounting point for the rear wheel spindle compared with common stock plastic parts.

The part is intended for hobby-scale RC use only and is sized to match the original-fit geometry listed in the product title. Installation is a like-for-like replacement procedure: remove the existing rear knuckle arm assembly, transfer any bearings or inserts as required, and secure the aluminium arm in the same mounting locations. Retain original hardware where possible to preserve alignment and fitment.

From a tuning perspective, swapping to an aluminium rear knuckle arm affects chassis stiffness and steering feedback at the rear axle. Builders who want crisper steering response or reduced flex under load will find aluminium arms useful as part of a broader setup change that may also include suspension arm geometry and shock tuning. Because the part changes structural stiffness rather than geometry, expect setup adjustments to suspension and toe to be done after fitment if driver feel is a priority.

This GPM aluminium rear knuckle arm is a straightforward aftermarket upgrade for modelers looking to increase rear-end rigidity and refine steering response on the WR02C Honda City Turbo chassis; fitment follows original mounting points for a direct swap.
