What fits your GLC: calipers, rotors and wheels
Front kits for the Mercedes-Benz GLC (X254, 2022–2026) come from AP Racing, Akebono, Alcon, Brembo, Endless and TTSPORT, with 4- to 10-piston calipers and 330–400 mm rotors. At the rear, Brembo and TTSPORT kits use 4-piston calipers and 360–380 mm rotors.
Wheel size narrows the list. With the recommended rotor, a few front kits need 17- or 18-inch wheels, but most need 19 or 20 inches. Rear kits need 19-inch wheels. Spoke shape and offset count as well, so share your wheel details when unsure.
Most kits come with brackets made for the GLC; a few on each axle are OEM-style direct mount and bolt to the factory caliper mounts. Some kits use genuine Mercedes-AMG or Cadillac calipers made by Brembo, and some front kits use genuine Audi calipers made by Akebono. Rotors are carbon ceramic or high-carbon steel, and nearly all kits are for the street.
