Choosing front brakes for the Cadillac CT4

AP Racing and TTSPORT supply the front kits matched to the Cadillac CT4 (2020–2023), with 4- or 6-piston calipers and 330–355 mm rotors recommended for this car. All of them mount on brackets made for the CT4 and are set up for street driving, with rotors in high-carbon steel or carbon ceramic.

Wheel clearance is easy to plan here. With the rotor we recommend for this car, every front kit fits an 18-inch wheel, and the smallest rotor also clears 17 inches. Spoke shape and offset still affect fit, so send us your wheel details if you are unsure and we will check before building.

A CT4 kit arrives complete for the front axle: calipers, rotors, pads, braided lines and the hardware and brackets to mount them. Build time is about 15 business days, as each kit is made to order. For a kit with no listed price, ask for a quote; our email reply comes within one business day.

Common questions — Cadillac CT4

Do CT4 big brake kits work with 17-inch wheels?

What rotor size is right for the Cadillac CT4?
We recommend 330–355 mm front rotors for this car, in high-carbon steel or carbon ceramic. Larger rotors would need bigger wheels, so match the rotor to the wheels you run and tell us both when ordering.
