Brembo 2PD.9031A3 GT Series Rear Big Brake Kit 380mm Type 3 Slotted 2-Piece Rotor Billet 4-Piston Silver Caliper

The Brembo 2PD.9031A3 is a Gran Turismo (GT) Series rear big brake kit featuring a billet monoblock 4-piston caliper paired with 380mm × 34mm 2-piece Type 3 slotted floating rotors finished with a silver powder-coat caliper. Engineered for serious performance enthusiasts and track-day drivers, this complete rear brake upgrade delivers a dramatic improvement in stopping power, pedal feel, and heat management over the factory braking system.

Key Features:

• Billet Monoblock 4-Piston Caliper (BM4): CNC-machined from a single billet of high-grade aluminum for maximum rigidity, minimal flex, and outstanding thermal resistance under extreme braking loads
• 380mm × 34mm 2-Piece Floating Rotor: Large-diameter cast iron disc mounted to a precision-milled billet aluminum center section; floating bobbin hardware allows the disc to expand radially and axially with heat, reducing warp and thermal cracking
• Type 3 Curved Slotted Rotor Face: Aggressive curved machined slots maximize cooling, continuously degas and refresh the pad surface, and deliver strong initial bite with excellent pedal modulation — ideal for high-performance street and track use
• Silver Powder-Coat Finish: Durable, corrosion-resistant caliper finish provides a premium look behind the wheel
• Differential Piston Bores: Eliminates pad taper wear for even, consistent pad contact across the full rotor sweep
• Twin Seal Design: Protects against debris intrusion and brake fluid contamination
• ABS & Traction Control Compatible: Designed to work seamlessly with factory ABS and electronic stability systems
• Complete Kit: Includes high-performance brake pads, metal-braided stainless steel brake lines (DOT/TÜV approved), caliper mounting brackets, and all necessary installation hardware
• 2-Year Warranty: Backed by Brembo's standard big brake kit warranty

The Brembo GT Series represents the Gran Turismo performance tier — purpose-built for drivers who demand the absolute best from their braking system on both public roads and the race circuit. The billet monoblock construction of the BM-series caliper is Brembo's most rigid and thermally capable caliper design in the GT lineup, making the 2PD.9031A3 an ideal choice for vehicles subjected to sustained high-speed braking.
