Girodisc 2022+ Cadillac CT4-V Blackwing Slotted Rear Rings
Girodisc slotted rear rotor rings deliver track-ready braking for 2022+ Cadillac CT4-V Blackwing models. These direct bolt-on replacements use a two-piece design with high-carbon steel friction rings mounted on OEM hats. Drivers gain reduced unsprung weight better heat dissipation and consistent stopping power under high loads.
Key Features
- Slotted Surfaces: Narrow slots on both sides clear water gases and debris for immediate bite and reduced fade during aggressive driving
