Brembo 2P1.8058A1 GT Rear Big Brake Kit 345x28mm Drilled 4-Piston Black Calipers

The Brembo 2P1.8058A1 is a complete rear axle GT Series Big Brake Kit featuring 4-piston cast monobloc radial mounted calipers and 345mm x 28mm (13.6-inch) 2-piece drilled rotors. Designed for the 2016 Porsche 981.1 Boxster Spyder (excluding PCCB-equipped models), this system delivers professional-grade braking performance for street, track, and race applications.

Key Features:

• Cast monobloc radial mounted 4-piston caliper body with black hard anodized finish
• 345x28mm (13.6") 2-piece cross-drilled rotors for enhanced cooling and degassing
• Aluminum alloy hat reduces unsprung mass for improved handling while reducing thermal stress
• Ships pre-assembled with all necessary hardware included for simplified installation
• Complete kit includes aluminum calipers, vented rotors, brake pads, stainless steel brake lines, and mounting hardware

Brembo Big Brake Kits offer increased thermal capacity to ensure consistent performance and reduce the risk of brake fade. The fixed caliper design improves durability and efficiency, with opposed pistons acting on pads with precision due to smaller piston diameters, resulting in more stable brake pedal pressure and enhanced pedal feel.

Application: Rear axle kit for 2016 Porsche 981.1 Boxster Spyder models without factory PCCB ceramic brakes. Part of Brembo's Gran Turismo series, engineered specifically for enthusiasts seeking professional-level braking performance for daily driving, spirited road use, and track applications.
