Special edition Tamiya 95121 HG Carbon Multi Roller Stay 1.5mm J-CUP 2019 - Japan Cup carbon upgrade  [95121]

Summary of the Tamiya 95121 HG Carbon Multi Roller Stay

Issued as part of the Japan Cup 2019 line, the Tamiya 95121 HG Carbon Multi Roller Setting Stay is a limited carbon component for Mini 4WD enthusiasts. At 1.5mm thickness it offers a lightweight, rigid option that often outperforms thicker FRP stays in handling response.

Construction and compatibility notes

The carbon surface carries a gold J-Cup/Tamiya insignia for a neat race aesthetic. It takes 9mm, 13mm and 19mm roller bearings so you can match roller diameter to track demands. While generally compatible with Mini 4WD and Mini 4WD PRO cars, some body or chassis combinations may need slight trimming for flush fitment.

Installation guidance and setup options

The HG Carbon Multi Roller Setting Stay is suitable for front or rear mounting to adjust cornering balance. Its updated profile removes elongated holes and improves long term durability. Multiple attachment points allow precise roller placement to help you tune cornering performance and vehicle stability across different track formats.
