The Brembo 1L3.9004A3 GT Big Brake Kit delivers race-proven stopping power with massive 380x34mm two-piece slotted rotors and high-performance aluminum calipers finished in silver. This complete front axle upgrade system represents Brembo's GT platform—engineered for enthusiasts who demand track-capable braking performance with reliable street manners.

Key Features:

• 380mm x 34mm two-piece Type-3 slotted brake rotors for superior heat dissipation and reduced unsprung weight
• Forged aluminum monobloc calipers with silver finish and six-piston design
• High-performance brake pads included, optimized for both street and track use
• Direct bolt-on installation designed for Porsche 996 GT2 (2002-2005), 996 GT3 (2004-2005), and 997 GT3 (2006-2009)
• Stainless steel braided brake lines for improved pedal feel and response
• All necessary mounting hardware and brackets included for complete installation

Brembo's two-piece rotor design separates the aluminum hat from the cast iron braking surface, reducing rotating mass while allowing for better thermal expansion management. The Type-3 slotting pattern efficiently evacuates brake dust and gases while maintaining consistent pad contact. This system provides significantly shorter stopping distances, improved fade resistance, and enhanced pedal modulation compared to factory brakes, making it ideal for high-performance street driving, canyon carving, and track day use.
