PARAGON 2-Piece Front Rotors – Mercedes-AMG A45 S (W177) / CLA 45 S (C118) / GLA 45 S (H247) – 360 x 36mm
These PARAGON 2-piece front rotors replace the factory rotors on the Mercedes-AMG A45 S (W177), CLA 45 (C118) and GLA 45 (H247) with a lighter floating assembly made for track days and spirited road driving. Sold as a pair, each 360 x 36mm rotor joins a slotted cast-iron ring to an aluminium hat to cut unsprung weight and resist fade and judder over long sessions.
Choose a black hardcoat anodised hat or a clear hard anodised hat. The clear finish holds its colour under extreme heat and is the better pick for track use, while the dyed black finish can discolour once temperatures pass about 260°C.
Note: The CLA 45 and GLA 45 must have the factory red calipers; the A45 S is the 4MATIC+ model. Bolts on with no modifications, works with the factory ABS and keeps the factory brake bias. Use OEM pads or aftermarket pads with the same pad depth. Installation by a professional is recommended.

- CM-250 high-carbon cast-iron rings, heat treated and CBN machined, run-out held within 0.03mm

- CNC-machined 6061-T6 aluminium hats, Mil-spec Type III hard anodised
- Weight 11.2 kg each, about 3.4 kg lighter than the factory rotor
