Tamiya 95122 HG Carbon Rear Multi Roller Stay 1.5mm J-CUP 2019 Off-Road Friendly Stay  [95122]

Intro to the HG Carbon rear multi roller stay (1.5mm) J-CUP 2019

The Tamiya 95122 HG Carbon Rear Multi Roller Stay is a 1.5mm carbon fibre accessory made for Mini 4WD hobbyists who want lighter, stiffer rear support. Released for Japan Cup 2019, it combines race styling with practical tuning points for serious setup work.

Style cues and roller hole layout

The stay shows a textured carbon pattern and gold J-CUP and Tamiya branding that underline its limited edition status. It is drilled to accept 9mm, 13mm, and 19mm roller bearings so you can tailor roll resistance and corner stability. There are also dedicated mount spots for mass dampers and brake parts to tame jumps and speed changes.

Compatible chassis models

Works with many Tamiya chassis types such as MA, MS, FM-A, AR, Super-II, Super XX, Super X, Super TZ-X, and VS. Some combinations will need minor trimming or alternate screw positions to suit your particular body and chassis layout.

Tuning for track performance

Ideal for those who test and tune frequently, the stay helps keep rear rigidity while offering multiple setup options to balance grip and velocity. Try different roller sizes to discover best lap times on technical circuits.
