Product Details

The Brembo GT Big Brake Kit delivers professional-grade stopping power with a complete bolt-on upgrade system. This kit features Brembo's renowned GT Series monobloc 4-piston calipers finished in white, paired with 345x28mm 2-piece Type 3 slotted rotors for exceptional heat dissipation and consistent braking performance.

Key Features:

  • Monobloc 4-piston aluminum calipers with white finish for maximum rigidity and style
  • 345x28mm (13.6x1.1 inch) 2-piece floating rotors with Type 3 slotted design
  • Two-piece rotor construction reduces unsprung weight and allows for thermal expansion
  • Directional slotted vane design improves pad bite and expels gases and debris
  • High-performance friction pads included, engineered specifically for this caliper design
  • Complete hardware kit with stainless steel brake lines for improved pedal feel
  • Direct bolt-on installation using factory mounting points

Brembo GT Systems represent the perfect balance between street usability and track performance. The larger rotor diameter and increased piston area provide significantly improved braking torque over stock systems, while the 2-piece floating design helps manage heat during aggressive driving. The Type 3 slot pattern is optimized for high-performance street and occasional track use, offering excellent initial bite and consistent pedal feel across a wide temperature range.

This front axle kit includes everything needed for installation: calipers, rotors, pads, stainless steel braided brake lines, mounting hardware, and detailed instructions. Professional installation is recommended.
