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
  • Curved Vane Design: Patented internal vanes direct air through the rotor for 20% faster cooling than straight vane competitors
  • High-Carbon Alloy: 48-series steel construction resists thermal cracking and warping even after repeated track sessions
  • Lightweight Build: Each ring weighs 17.2 lbs for 4.8 lbs savings per side over OEM 22 lbs rotors totaling 9.6 lbs less unsprung mass per axle
  • Precision Dimensions: 380mm x 30mm size matches OEM specs with floating two-piece setup that expands/contracts independently to prevent hat-ring separation

Product Notes

  • Sold as a pair for complete rear axle upgrade
  • Compatible with OEM calipers pads and ABS systems
  • Follow Girodisc bed-in procedure for peak performance: 10-10-3 cycles of progressive stops

Installation Notes

Brake Rotors

Brake Rotors

Brake rotors work with brake pads to bring your vehicle to a controlled stop. Upgrading from worn or stock rotors to a performance or OE-quality replacement improves braking consistency, reduces fade, and restores the original factory feel. Popular ProductsPopular brake rotor choices include EBC Brakes USR slotted rotors, Brembo OE-replacement rotors, StopTech Sport cross-drilled and slotted rotors, and Centric Premium rotors for OE-quality service replacement. What is the difference between slotted, drilled, and blank rotors?Blank rotors are standard OE-style with no machining, suitable for daily drivers. Slotted rotors have channels cut into the face for debris evacuation and improved high-heat performance. Cross-drilled and slotted rotors combine both features but may crack under extreme track use. How do I know when brake rotors need replacement?Replace rotors when rotor thickness falls below the minimum spec stamped on the rotor hat, when lateral runout exceeds 0.003 inches, or...

GiroDisc

GiroDisc

GiroDisc manufactures premium two-piece floating brake rotors designed for performance street and track applications where reduced unsprung weight, superior thermal management, and consistent pedal feel under repeated hard braking are required. The two-piece design separates the cast iron friction ring from the aluminum hat using a patented floater system that allows the rotor to expand thermally without transmitting warping stress to the hub, eliminating the judder and pedal pulsation that single-piece rotors develop after repeated track sessions. GiroDisc rotors are available for a wide range of European and Japanese sports cars including Porsche, BMW M, Ferrari, Lamborghini, and the Subaru WRX, targeting enthusiasts and racers who demand the same engineering quality in their brake hardware as in their suspension and engine components. The significant weight reduction compared to equivalent cast iron rotors improves both acceleration and braking response by reducing the rotational...
