Picking calipers and rotors for the GX550

Front kits for the Lexus GX550 (2024–2026) come from Akebono, Brembo and TTSPORT, with 6-, 8- or 10-piston calipers and 345–440 mm rotors on this car. At the rear, Brembo and TTSPORT use 4-piston calipers with 355–410 mm rotors. Both axles offer high-carbon steel or carbon ceramic rotors.

Most kits mount on brackets made for the GX550, while OEM-style direct-mount front kits bolt to the factory caliper mounts. Some kits use genuine Audi calipers made by Akebono (front) or by Brembo (rear), and both axles offer genuine Cadillac calipers made by Brembo. Front kits are street setups; the rear includes a track kit.

With the rotors we suggest, a few front kits need 18-inch wheels, while most need 19 to 22 inches. At the rear, the smallest kit needs 18 inches and the others need 19 to 21. Offset and spoke shape play into clearance as well; if you are unsure, send us your wheel details.
