What makes it special

Using Alcon’s race-bred CAR97 caliper architecture and Paragon’s lightweight floating rotor technology, this front brake conversion delivers consistent pedal travel and outstanding heat rejection. The floating T-bobbin rotor-to-hat interface with 12-bolt mounting helps control thermal expansion, keeping the disc true under heavy use. The result is repeatable performance lap after lap, yet perfectly civilised on the daily drive.
