This steel brake disk is supplied to replace worn rotors on HPI Savage 21 chassis, offering a direct-fit option for models that reference the Savage 21 platform.
Installation overview: remove the wheel and existing rotor, position the new steel disk in the factory orientation, and secure the hub fasteners to the specified fitment. After installation, confirm rotor runout and pad alignment before operating the model.
Tuning role and durability: steel discs provide repeatable wear characteristics that help when dialling in brake feel. Regular inspection for scoring or uneven wear will ensure safe, predictable braking and guide replacement intervals.
