The Brembo big brake kit for Porsche Boxster S (986, 1997–2004) upgrades rear braking with four‑piston cast calipers and two‑piece 345×28 mm rotors. This GTS rear kit uses drilled rotors and a black HA finish to aid heat dissipation and pad bite under repeated stops. It’s specified for the 986 Boxster S rear application to provide a stronger, more consistent braking setup.
