The Brembo GTS rear big brake kit for 2008–2012 Quattroporte applications upgrades the rear with a four‑piston cast caliper and two‑piece 380 x 28 mm drilled rotors in black. Intended as a direct‑fit rear replacement, the kit trades stock rear components for larger calipers and two‑piece rotors to help achieve improved balance and consistent pedal feedback when paired with compatible front brakes.
