Includes mounting brackets and hardware. Designed to work with the factory ABS brake system. Spoon Monobloc calipers provide the highest rigidity and lowest weight by reducing amount of assembly hardware. Unsprung weight is reduced to provide faster suspension response and better handling. 4 opposing pistons with differential bores provides better pedal feel with smooth and consistent braking. The rigid caliper structure also reduces pad taper. S2000 OEM sized pads can be used. Allows for rotor diameter up to 300mm and 26mm thick. Each caliper weighs only 2.6 kg. Please check wheel and fender clearances before using.
