PARAGON 2-Piece Rear Rotors – Mercedes-AMG A45 S (W177) / CLA 45 S (C118) / GLA 45 S (H247) – 330 x 22mm
These Paragon 2-piece rear rotors are a direct replacement for the factory rear discs on the current Mercedes-AMG A45 S, CLA 45 and GLA 45. Directional ventilation vanes help the rotor run up to 30% cooler than OEM, and the floating design allows the ring to expand without distorting, reducing fade and judder over long sessions.
Each 330 x 22mm assembly weighs 5.4 kg, about 4.7 lb less than the OEM rotor, which cuts unsprung and rotating mass. The slotted CM-250 cast iron ring is joined to a 6061-T6 aluminium hat by a 10-bolt short D-Bobbin system. Hats come in clear hard anodised (best for track, will not discolour) or black dyed hardcoat (may discolour above 260°C).
Note: CLA 45 and GLA 45 fitment is for vehicles with OEM red calipers. Compatible with OEM or aftermarket pads of the same pad depth. Installation by a professional is recommended.
