Associated RC18T Alloy Rear Sinkage Dish Rim by GPM AR0017R  [AR0017R]

Rear alloy sinkage dish rim

The GPM AR0017R is an aftermarket alloy rear sinkage dish rim produced for the Associated RC18T platform, supplied as a matched pair intended for RC-scale use only. It targets builders who replace worn plastic rims or pursue a stiffer wheel mounting surface for setup consistency on 1/18 scale short-course and touring truck style chassis.

This rim focuses on mechanical fit and tuning role rather than cosmetic change. In practical terms it provides a rigid mount surface for the tyre bead, helping maintain consistent tyre shape under cornering loads and permitting fine adjustment of offset and track width when paired with appropriate wheel hexes and spacers.

Installation is standard wheel-swap procedure: remove the wheel assembly from the hub, transfer tyre and any foam insert if needed, fit the alloy rim onto the wheel hex and verify runout and clearance before final tightening. Check hex engagement and wheel nut torque after a short test run to confirm secure seating.
