The Tamiya 15530 FRP Reinforcing Plate Set is a practical upgrade for Mini 4WD models that need firmer roller stay mounting. Intended for 13mm and 19mm roller setups, these plates provide a stable base that reduces flex in crucial stay areas.
Fabricated from FRP, the plates offer a reliable combination of durability and lightness. They are compatible with a wide variety of Tamiya Mini 4WD chassis, making them suitable for many common builds and upgrade paths.
The main advantage is improved consistency in roller alignment, which lowers the chance of rollers slipping off on sharp corners or rough sections. That consistency helps drivers maintain predictable handling at high speed.
Fitting requires basic tools and no complex modifications. Secure the plates evenly and recheck for any rubbing around rollers and spacers after first runs. Periodic checks will keep performance consistent.
