PARAGON 2-Piece Front Rotors – Honda S2000 (AP1/AP2) – 300 x 25.4mm
A 300 x 25.4mm two-piece front rotor pair for the Honda S2000 (AP1 and AP2). At 6.05 kg each they shed about 0.5 kg a corner over the factory discs, and the floating ring keeps braking stable through repeated hard stops on the street or at the circuit.
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 with no modifications. 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.
Features
- 300 x 25.4mm front pair, 6.05 kg each (about 0.5 kg lighter than OEM)

- CM-250 high-carbon alloy cast iron rings, heat treated to relieve stress and CBN machined flat

- Directional internal vanes help the rotor run up to 30% cooler than the factory disc
- Lateral run-out held to 0.03mm or less and each rotor balanced within 2 g to keep vibration down
