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

  • 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
