Brembo 2P1.8042A5 Gran Turismo 4-Piston Rear Brake Kit Yellow Drilled 345mm

The Brembo 2P1.8042A5 Gran Turismo Big Brake Kit delivers professional-grade stopping power and track-proven performance for rear brake upgrades. This complete bolt-on system features 4-piston fixed calipers in eye-catching yellow finish paired with 345mm cross-drilled two-piece rotors, providing exceptional thermal capacity and brake torque compared to stock brake systems.

Two-Piece Floating Rotor Design

The floating two-piece rotor assembly separates the brake hat from the rotor disc, reducing unsprung and rotating weight while dramatically improving heat dissipation. This advanced design increases resistance to thermal cracking by over 40% compared to conventional one-piece rotors. The cross-drilled rotor surface features precision-machined holes that evacuate brake gases, water, and pad residue, maintaining consistent pedal feel during aggressive driving and track use.

4-Piston Fixed Caliper Performance

The lightweight aluminum calipers utilize four sequentially-sized pistons to distribute clamping force evenly across the brake pad surface. This fixed-mount design eliminates caliper flex found in sliding caliper systems, delivering superior pedal response and modulation. The yellow powder-coated finish showcases the iconic Brembo logo while providing long-lasting corrosion resistance.

Complete Brake System Kit Includes:

• Brembo 4-piston aluminum calipers with yellow finish
• 345mm x 28mm cross-drilled two-piece rotors (13.6" x 1.1")
• High-performance brake pads with application-specific friction material
• DOT/TÜV approved stainless steel braided brake lines
• Billet aluminum caliper mounting brackets
• Anti-rattle hardware and all necessary installation fasteners

Key Features and Benefits

• Increased Stopping Power: Larger rotor diameter provides greater leverage and brake torque
• Improved Heat Management: Enhanced thermal capacity prevents brake fade during spirited driving
• Weight Reduction: Two-piece design reduces unsprung mass for improved handling response
• Enhanced Cooling: Directional vane design and cross-drilling maximize heat evacuation
• ABS Compatible: Fully compatible with factory ABS and traction control systems
• Track-Ready: Designed for high-performance street use and track day applications
• Direct Bolt-On: Complete hardware included for seamless installation

Important: Aftermarket wheels with proper clearance are required. Measure wheel clearance carefully before installation to ensure proper fitment with the larger caliper and rotor assembly. As a general guideline, the rotor diameter should be approximately 4 inches smaller than your wheel diameter.

Brembo Gran Turismo brake systems represent the pinnacle of aftermarket brake technology, combining race-proven engineering with street-friendly reliability. Each kit undergoes rigorous testing to ensure seamless integration with your vehicle's braking system while delivering the performance advantage that has made Brembo the choice of world-class racing teams and premium automotive manufacturers worldwide.
