Overview of the Tamiya 95179 Jr HG Carbon Rear Roller Stay
The Tamiya 95179 Jr HG Carbon Rear Roller Stay is a purpose-built upgrade for Mini 4WD hobbyists who want a blend of looks and function. Released as a limited run for the Japan Cup 2025, it pairs a recognisable commemorative aesthetic with usable on-track benefits.
Visual styling and build materials
This rear roller stay uses rigid carbon fiber with an angled profile to give a bold, aggressive stance on Mini 4WD builds. The plate is strong and lightweight, and it carries a black carbon weave with mint green Japan Cup and Tamiya logos for instant recognition on the pit table.
Which chassis it will work with
Fitment covers a broad range: VZ, FM-A, MA, AR, MS, VS, Super-II, Super X, Super XX and Super TZ-X. Depending on body mounts and bumper setups you may need small adjustments to clear certain combinations.
How it helps on the track
Besides the visual upgrade, the Tamiya 95179 part stiffens the rear bumper area and helps the rollers track more consistently. Racers report improved resilience to light impacts and steadier cornering when rollers are tuned correctly.
Installation notes for quick upgrades
The plate lines up with the hole pattern used by the JR FRP Rear Plate on Super X chassis, making for a straightforward swap in many cases. Basic tools and common Mini 4WD hardware are all you need to fit it and get back to testing.
