Paragon 6-Piston Front Big Brake Kit – Ford Focus ST / RS Mk3

This complete, track-ready front big brake kit is designed for the Ford Focus ST and RS Mk3, offering a major upgrade in braking power, thermal control, and pedal feel. Built around Paragon’s PA015 or PA035 6-piston calipers, this system is engineered for aggressive street driving and dedicated track use. The only difference between the two caliper models is the maximum rotor size supported—offering flexibility for different build requirements.

  Note: PA015 and PA035 calipers differ only in the maximum rotor size supported
• Fully-floating 2-piece slotted rotors with directional curved ventilation vanes
• Up to 30% cooler rotor operation compared to OEM
• Caliper finish options: hard-anodised or ENP electroless nickel plating
• Hard-anodised 6061-T6 aluminium rotor hats for improved resistance to heat, wear, and discolouration
• Piston sizes optimised for Focus ST / RS Mk3 – fully compatible with OEM ABS and master cylinder
