PARAGON 2-Piece Rear Rotors (Iron Conversion) Porsche Cayman GT4 (981/718) 390 x 32mm

PARAGON 2-Piece Rear Rotors (Iron Conversion) – Porsche Cayman GT4 (981/718) – 390 x 32mm

These Paragon 2-piece rear rotors convert the Porsche 981 and 718 Cayman GT4 from factory ceramic composite (PCCB) rear discs to iron, giving a more durable, lower-cost option for regular track use. Directional ventilation vanes help the rotor run up to 30% cooler than OEM and resist thermal cracking under repeated heavy braking.

The 390 x 32mm slotted CM-250 cast iron ring floats on a CNC-machined 6061-T6 aluminium hat via a 12-bolt short D-Bobbin system. Two hat finishes are offered: black hard anodised (P2R.221.390.320.23370.09.01.01.R) and clear hard anodised (P2R.221.390.320.23370.09.01.02.R), which withstands the highest track temperatures; black hats may discolour above 260°C.

Note: For vehicles originally fitted with factory ceramic brakes (PCCB). Direct bolt-on and maintains OEM brake bias and ABS function. Installation by a professional is recommended.
