Paragon 2-Piece Rear Brake Rotor Pair - Mercedes-Benz CLA 45 C117 / A45 W176 AMG - 330x22mm

Upgrade the rear braking performance of your Mercedes-Benz CLA 45 (C117) or A45 (W176) AMG with Paragon Performance 2-Piece Rotors. Engineered for demanding track and race conditions, these 330mm slotted rotors feature a floating 2-piece design with directional ventilation vanes for superior heat dissipation, reduced brake fade, and improved pedal feel during high-performance driving.

Manufactured from CM-250 high carbon alloy cast iron, each rotor undergoes stress-relief heat treatment and precision CBN machining to ensure optimal balance, minimal run-out (≤ 0.03mm), and smooth bedding with new pads. The lightweight 6061-T6 aerospace-grade aluminium hats are CNC machined and hard anodised for maximum strength, corrosion resistance, and thermal durability under extreme conditions. Slotted faces enhance wet-weather performance and keep pad surfaces clean for consistent bite.

Compatible with OEM brake pads and ABS systems, these rotors offer a true bolt-on upgrade with a 23% reduction in unsprung weight compared to factory discs. Also fits the 2014–2018 GLA 45 AMG (X156).
