To celebrate Waigo Hobby’s 50th anniversary in 2026, we’re launching a limited-edition HG Carbon Tune-up Part in a brand-new color scheme! 92449 HG Carbon Wide Rear Stay (3mm/Silver) Waigo Hobby marks Tamiya’s first use of silver carbon fiber stay paired with purple lettering, making it truly one-of-a-kind among tune-up parts! The 3mm silver carbon fiber parts are a rare specification that hasn’t been released in over a decade! This gives this limited edition product not only practical value but also added commemorative significance. The 3mm thickness offers greater rigidity compared to the standard 1.5mm carbon fiber plates on the market. It can replace modifications involving layered 1.5mm sheets, and the one-piece 3mm design provides enhanced strength and impact resistance. Additionally, the 3mm carbon fiber stay opens up new possibilities for parts selection in Stock Class competitions.

★This 1.5mm stay can be fitted to your Fully Cowled Mini 4WD Series car without the need for any modifications!
★It commemorates thirty years of the Series, and features a rather special silver color carbon fiber pattern plus wording printed in blue.
★Sporting refined lines, it has holes for the attachment of 9mm, 13mm and 19mm rollers to ensure there are setup options aplenty.
★The stay can also be attached to the underside of your car to lessen the likelihood of getting stuck on the course fence.
