The stay and roller mount sections can be separated and reassembled in different combinations, giving a wide range of roller height and angle settings.
Unlike the near-universal FRP multi roller stays, this carbon stay's listed compatibility is narrower — Type 5, Zero, FM, Super-1, Super-II, Super FM, Super X, Super XX, Super TZ-X, and VS chassis only — since its three-point rear mounting pattern matches that particular run of chassis generations rather than the newer MS, AR, MA, VZ, or ME line. The included 11mm and 17mm rollers cover both a tight cornering setting and a wider one without needing rollers bought separately.

Roller choice on a Tamiya 3-lane layout is about controlled wall contact. Heights, sizes and stagger that keep the car settled through tight bends.
Five-lane layouts are faster and more open, so roller setup shifts toward stability at speed. Sizes, heights and damping that survive big sections.
