Race-ready Tamiya 95121 HG Carbon Multi Roller Stay 1.5mm J-CUP 2019 - lightweight Japan Cup tuner  [95121]

Performance profile for the Tamiya 95121 HG Carbon Multi Roller Stay

This limited Japan Cup 2019 component is the Tamiya 95121 HG Carbon Multi Roller Setting Stay, produced for Mini 4WD fans who want a balance of low mass and durability. Its 1.5mm carbon construction cuts weight compared to FRP while keeping stiffness for sharper lap times on competitive circuits.

Finish, fitment and roller options

The stay shows a refined carbon surface with a gold J-Cup/Tamiya marking that upgrades the look as well as the function. It accepts 9mm, 13mm and 19mm roller bearings so you can dial in your setup for different track sections. It will work with Mini 4WD and Mini 4WD PRO cars, though certain chassis or bodies may need small clearances or trimming for ideal installation.

Mounting choices and setup advice

You can fit the HG Carbon Multi Roller Setting Stay at the front or rear to tune handling balance. The revised shape and removal of elongated holes increases robustness under high speed, and the multiple mounting points let you experiment with roller positions to improve cornering and stability across various track layouts.
