This complete, pre-assembled rear big brake kit for the Porsche 981 Boxster and Cayman pairs Paragon's PA025 4-piston rear calipers with fully floating 2-piece rotors. It is built for track day drivers and fast road use, giving strong bite, responsive modulation and reliable heat resistance through long sessions.
Choose 355 x 32mm or 380 x 32mm rotors, hard anodised or ENP caliper finish, and Paragon P2, P3, R5 or R7 pads.
