GiroDisc 2021+ Cadillac CT4-V Blackwing Slotted Rear Rings

This is a set of rear slotted rotor rings from GiroDisc, specifically made for the 2021 and newer Cadillac CT4-V Blackwing. These are designed to replace the factory rotor rings, offering improved performance for drivers who push their cars hard. The slotted design helps manage heat and clear out dust and gas, which means more consistent braking when you need it most, especially during spirited driving or track use.

GiroDisc is known for making well-built brake components, and these rotor rings are no exception. They are constructed from a high-carbon iron alloy that's chosen for its durability and ability to handle the stresses of repeated braking. The slots themselves are precisely machined to help vent gases and debris away from the pad surface, preventing glazing and maintaining optimal friction. This is a critical upgrade if you're looking to get the most out of your CT4-V Blackwing's braking system, especially if you've already upgraded other components or plan to use the car in demanding situations. Remember, these are just the rotor rings, so you'll need to reuse your existing aluminum hats or purchase compatible ones separately.

When installing these, make sure to follow the manufacturer's instructions carefully. Proper bedding-in procedures are essential to ensure the new pads and rotors work together effectively and to achieve the best possible performance and longevity from your braking system. If you're unsure about the installation process, it's always a good idea to have a qualified mechanic handle it to ensure everything is torqued correctly and the system is bled properly.
