The Brembo 3KC.9046AZ is a GT-R Series Big Brake Kit engineered for drivers who demand race-proven stopping power on the street or track. Part of Brembo's renowned GT-R lineup, this kit upgrades the entire brake corner with a matched caliper, rotor, and hardware assembly built to Brembo's exacting motorsport standards.

Key Features:

• GT-R Series 4-Piston Caliper: Rigid, lightweight aluminum construction delivers consistent pedal feel and exceptional clamping force under repeated hard stops
