Brembo 2S1.9004A2 GT Big Brake Kit Rear 380x28mm 2-Piece Drilled Rotors Red Calipers

The Brembo GT Big Brake Kit delivers race-proven stopping power and improved thermal management for high-performance driving. This rear axle system features Brembo's BM4 four-piston monobloc calipers finished in signature red, paired with massive 380x28mm two-piece floating rotors with cross-drilled ventilation.

Key Features:

• 380mm x 28mm two-piece floating rotors with cross-drilled design for superior heat dissipation
• BM4 monobloc four-piston aluminum calipers with high-temperature red finish
• Two-piece rotor design reduces unsprung weight while maintaining thermal stability
• Direct bolt-on installation for Porsche Panamera S, 4S, and Turbo models (2009-2016)
• Includes stainless steel braided brake lines for improved pedal feel
• Complete hardware kit with DOT-approved components
• Designed and manufactured in Italy to OE and motorsport standards

Brembo GT systems are engineered for enthusiasts who demand maximum braking performance on both street and track. The larger rotor diameter and increased piston area provide significantly improved stopping power and fade resistance compared to factory brakes. The two-piece rotor construction allows the aluminum hat to isolate heat from the wheel bearing while reducing rotational mass for better acceleration and handling response.

This kit is specifically engineered for the rear axle and must be paired with an appropriate front brake upgrade for balanced braking performance. Professional installation is recommended to ensure proper fitment and bleeding procedures.
