22-23+ Cadillac CT4-V Blackwing Rear 2-Piece Rotors (Includes 2) - GiroDisc



FITS 2022+ CADILLAC CT4-V ( BLACKWING )
DESCRIPTION:
Upgrade the rear braking system of your 2022+ Cadillac CT4-V Blackwing with the Girodisc A2-318 2-Piece Rear Rotors. Designed as a direct replacement for the factory rear brake rotors, these fully floating assemblies reduce unsprung weight and rotating mass while delivering improved durability and heat management for performance street driving and track use. The rotor rings are machined from Girodisc's proprietary high-carbon iron casting and feature 48 curved internal vanes that act as a centrifugal pump, pulling cooling air through the hub to help control rotor temperatures during hard braking. Each rotor uses a reusable 6061-T6 aluminum center hat with a black anodized finish for durability and corrosion resistance. Girodisc manufactures the major components, including the hats, rotor rings, and drive pins, in-house at its Bellingham, Washington facility using domestically sourced materials. The serviceable two-piece design also allows worn friction rings to be replaced independently while retaining the aluminum center hats.

- Girodisc recommends replacing the rotor rings once they reach a minimum thickness of 26mm or if a crack extends to the edge of the rotor ring.
- The aluminum center hats are reusable when the friction rings eventually require replacement.
