Tamiya 92449 HG Carbon Wide Rear Stay - 1/32 Mini 4WD rear stay for common racing chassis, 3mm silver carbon  [92449]

Tamiya 92449 HG Carbon Wide Rear Stay (3mm/Silver)

The Tamiya 92449 HG Carbon Wide Rear Stay is a limited-edition tune-up part released for Waigo Hobby's anniversary. The component uses a silver-toned carbon fiber plate at a 3mm thickness, presented as a single-piece rear stay rather than layered thinner plates. The finish and purple lettering identify this run as a commemorative item rather than a standard parts release.

In practical terms, the one-piece 3mm construction increases stiffness compared with typical 1.5mm carbon plates and common stacked configurations. The increased rigidity alters the structural response of the rear stay assembly, which builders should consider when matching roll and flex characteristics across a tuned chassis.

Fitment and installation follow the standard rear stay mounting approach used on many performance-oriented Mini 4WD chassis. Before installation, verify hole spacing and screw types against your chassis to avoid fitment issues. The part's material and single-piece construction also change impact resistance compared with layered assemblies.

Collectors and hobbyists noting rarity will find the silver carbon finish and Waigo Hobby branding the primary reasons for interest. The part may serve as a visual upgrade or a replacement where a stiffer, single-piece rear stay is desired, but it should be selected with attention to overall chassis setup.
