Since the genuine rotor has worn out, I replaced it with a sports brake rotor.By making it new, the rotor and the pad hit more firmly than before, so the brakes worked well.
Since the bell housing is made of aluminum, it is a little lighter than the stock brake rotor, which contributes to the unsprung weight.
Also, since it is a 2-piece, you can purchase a repair rotor the next time you replace it, so it is good in terms of cost.
