Brembo 3K3.9073AZ PISTA 6 TY3 Front Brake Disc Set 380x35mm 2-Piece

The Brembo 3K3.9073AZ PISTA racing brake disc set represents the pinnacle of motorsport braking technology, designed for high-performance track applications and professional racing. This front axle system features 380mm diameter 2-piece rotors with the advanced TY3 slotting pattern that has proven itself in GT racing and endurance events worldwide.

Advanced TY3 Slotting Technology:

The TY3 disc design features aggressive groove machining that delivers high initial bite with excellent modulation characteristics. This slot pattern continuously refreshes the pad's friction surface, removes dirt and glazing residues, and delivers firm, reliable bite from the first moment of braking. The Type 3 slotting architecture uses grooves of differing sizes and orientations to optimize disc-pad contact under extreme racing conditions.
