The Brembo GTS big brake kit for 2009–2015 Cadillac CTS‑V is a front 6‑piston cast caliper package with 405x34 mm two-piece drilled rotors in black. Drilled rotor faces help vent gases and surface heat while the two-piece hat-and-ring construction enables economical replacement of worn rings. This configuration offers CTS‑V drivers a serviceable upgrade for firmer, more consistent front braking.
