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.
