PARAGON 2-Piece Rear Rotors – Honda Civic Type R (FK8/FL5) – 305 x 11mm
A 305 x 11mm two-piece rear rotor pair for the Honda Civic Type R FK8 and FL5. A solid slotted iron ring is bolted to a fixed aluminium hat, bringing each rotor down to 4 kg, about 1.4 kg less than the factory part, for better heat resistance and less unsprung weight at the track.
Two hat finishes are offered. Mil-Spec Hard Coat (clear) anodising keeps its colour under track heat and is the one to pick for circuit work. Mil-Spec Black Coat (dyed) anodising can discolour above 260°C, so it suits street and mixed use.
Note: A direct bolt-on rear replacement with no modifications. The hat is fixed (non-floating). Works with the factory calipers, ABS and brake bias, and takes OEM or aftermarket pads of the same pad depth as the originals. Installation by a professional is recommended.
