Brembo 2S2.9013A6 GT Rear Brake Kit 380x28mm 2-Piece Slotted Rotors White BM4 Calipers

The Brembo 2S2.9013A6 GT Brake Kit delivers motorsport-derived performance for both street driving and demanding track use. This complete rear axle upgrade system features Brembo's advanced BM4 four-piston calipers paired with oversized 380mm x 28mm two-piece floating rotors with Type 1 slotted finish, providing dramatically improved braking power, heat dissipation, and fade resistance over stock braking systems.

BM4 Caliper Technology:

• Cast aluminum four-piston fixed caliper with opposed pistons for even pad wear and uniform clamping force
• Innovative 4D casting technology with internal fluid passages eliminates external brake lines for cleaner aesthetics
• Single integrated bleed point simplifies maintenance
• White powder-coated finish with Brembo logo for eye-catching appearance
• Radial mounting design ensures superior rigidity and minimized deflection under hard braking

Two-Piece Floating Rotor Design:

• 380mm diameter x 28mm thick vented rotors (15 inches) for increased thermal capacity
• Aluminum alloy center bell reduces unsprung weight while improving heat dissipation
• Type 1 slotted pattern continuously refreshes pad surface, removes debris, and maintains consistent friction coefficient
• Proprietary ventilation system improves cooling capacity and increases thermal shock resistance by over 40%
• Cast iron rotor rings made from Brembo's specialized alloy for extended service life

Complete Kit Includes:

• Pair of BM4 four-piston white calipers for rear axle
• Two 380x28mm two-piece slotted rotors
• High-performance brake pads optimized for street and track use
• Stainless steel braided brake lines for improved pedal feel and response
• CNC-machined caliper mounting brackets and adapters
• Complete hardware kit for secure installation

This Brembo GT system integrates seamlessly with factory master cylinders, ABS, and traction control systems. The fixed caliper design with multiple opposed pistons delivers more immediate and decisive braking response, while the oversized rotors provide greater braking torque and superior thermal management for consistent performance during consecutive track sessions or aggressive street driving.
