Brembo 2P3.8067A2 GT Series M4 Rear Big Brake Kit 345x28mm 2-Piece Slotted Rotors Red 4-Piston Calipers

The Brembo 2P3.8067A2 GT Series rear big brake kit delivers motorsport-derived braking performance for street and track use. Featuring the M4 4-piston monobloc caliper in a bold red finish, this rear axle kit is engineered around 345mm x 28mm (13.6") 2-piece floating discs with a Type 3 slotted vane design for maximum heat dissipation and consistent pedal feel under demanding conditions.

Key Features:

• M4 Cast Monobloc Radial-Mount Calipers — 4-piston opposed design with red anodized aluminum finish; proven across Brembo's Gran Turismo caliper family
• 345mm x 28mm 2-Piece Floating Discs — Advanced high-carbon alloy iron friction ring with corrosion-resistant plating, mounted to a lightweight aluminum hat via floating D-Bobbin anti-rattle hardware
• Type 3 Slotted Disc Design — Curved 48-vane ventilated rotor construction promotes aggressive gas and heat evacuation for reduced fade during repeated hard stops
• High-Performance Brake Pads Included — Optimized compound for both street and track use
• Metal-Braided Brake Hoses Included — Goodridge-style braided stainless lines for firm, consistent pedal response
• Complete Hardware Kit Included — All mounting hardware, anti-squeal shims, and fasteners supplied for a complete axle installation
• Street & Track Rated — Designed for high thermal resistance and precise brake modulation across a full range of driving conditions

The Brembo GT system represents the benchmark in aftermarket big brake technology, with the M4 caliper platform wrapping disc sizes from 328mm to 380mm and sharing the same proven architecture used in Brembo's top-tier motorsport programs. The 2-piece disc construction increases thermal capacity over solid OEM rotors, dramatically reducing brake fade under repeated high-heat braking events.
