Brembo 2P1.8503A3 GT Rear Big Brake Kit 365x29mm 2-Piece Drilled Rotors Silver M4 Calipers

The Brembo 2P1.8503A3 GT Big Brake Kit delivers motorsport-derived braking performance for enthusiasts seeking superior stopping power, improved heat management, and distinctive style. This complete rear axle brake system features professional-grade components engineered to enhance braking performance for both spirited daily driving and track day use.

Key Features:

• 4-piston cast monoblock M4 calipers machined from aluminum for exceptional rigidity and minimal deformation under extreme braking conditions
• 365x29mm (14.4-inch) 2-piece drilled rotors with floating disc design allowing radial and axial movement for thermal expansion
• Drilled rotor pattern effectively dissipates brake gases, removes excess pad material, and channels away water for consistent performance
• Radial-mounted fixed calipers with opposed piston design for uniform pad wear and enhanced brake force distribution
• Silver powder-coated caliper finish with distinctive Brembo logo for premium appearance through wheel spokes
• Lightweight aluminum hat section reduces unsprung weight compared to factory components
• Proprietary anti-rattle floating disc hardware eliminates noise typically associated with 2-piece rotors
• High-performance brake pads engineered specifically for GT applications
• Stainless steel braided brake lines by Goodridge for firm, responsive pedal feel with reduced brake fluid expansion
• CNC-machined billet aluminum caliper adapters with complete installation hardware included

The monoblock M4 caliper design represents a significant upgrade over 2-piece calipers, offering superior stiffness and heat resistance for drivers who demand consistent braking performance during aggressive driving. The oversized 365mm rotors provide increased thermal capacity and braking torque, dramatically reducing brake fade while improving pedal modulation and response. This complete kit arrives pre-assembled and ready for installation, bringing Brembo's proven racing technology to your rear axle.
