Associated RC18T Precision Alloy Sinkage Rims (6 Poles) AR0603 by GPM  [AR0603]

Precision alloy sinkage rims

These alloy rims are supplied as a matched pair for the Associated RC18T and are intended as a direct replacement for worn plastic or metal wheels. They are engineered for consistent wheel offset and accurate hub seating while providing increased rim stiffness that influences setup tuning. The six-pole geometry denotes the rim mounting pattern and how radial loads transfer into the hub interface.

Fitting is carried out using standard wheel removal and refit procedures: remove the original assemblies, align the rim to the wheel hex and hub, and secure with the original mounting hardware. After installation, confirm rotational clearance, torque on fasteners, and wheel balance to reduce vibration. These rims are aimed at hobbyists seeking reliable, repeatable changes to wheel stiffness and mass distribution for handling refinement.

As a durable alloy upgrade for the RC18T, this rim set supports consistent tuning outcomes by changing stiffness and mass characteristics at the wheel assembly.
