GiroDisc 2021+ Cadillac CT4-V Blackwing Slotted Rear Rotors
GiroDisc slotted rear rotors provide a direct bolt-on upgrade for the 2021+ Cadillac CT4-V Blackwing. The two-piece assembly features a lightweight 6061-T6 aluminum hat mated to a high-carbon slotted cast iron ring for reduced unsprung weight and improved heat dissipation. Drivers experience consistent braking with less fade during aggressive use.
Key Features
- Two-Piece Construction: Aluminum hat and cast iron ring cut 4.9 lbs per rotor (9.8 lbs total rear) to sharpen handling response and suspension feel
- Slotted Friction Surface: Cuts through water film and clears pad gases for immediate bite and reliable stopping power in wet or dry conditions
- Curved Vane Core: Channels air through vents to pull heat from the rotor center and maintain pad effectiveness under load
- Stainless Steel Hardware: Aircraft-grade bobbins and bushings create a floating mount that absorbs expansion and prevents hat distortion
- Precision Engineering: CAD-designed at 370mm x 32mm to match OEM specs with perfect balance and hub centering
