No. The D1-117 rings are designed only for Girodisc aluminum hats and cannot mount to OEM one-piece or carbon-ceramic assemblies. Which brake pads are best for these rotors? For street performance, use Ferodo DS2500 or Hawk HPS 5.0. For track driving, Pagid RS29 or Hawk DTC-70 deliver excellent high-temperature stability and modulation. Do I need to bed the rotors before track use? Yes. Perform 8–10 medium-pressure stops from 60 mph to evenly transfer pad material to the rotor, then allow the brakes to cool before full use. Are these rotors directional? Yes. Each ring is marked for left and right installation. Proper orientation ensures correct airflow through the internal vanes for maximum cooling.
