Brembo 1MD.9058AS GT-S Big Brake Kit Drilled 2-Piece Rotor with Monobloc Caliper

The Brembo 1MD.9058AS is a GT-S Series Big Brake Kit (BBK) engineered to deliver a substantial upgrade over factory braking systems. Developed from Brembo's decades of motorsport and OEM expertise, this complete kit replaces the entire brake corner assembly with high-performance components designed for both demanding street use and track-day sessions.

Key Features:

• GT-S Series Monobloc Caliper: Cast from a single billet of aluminum for outstanding rigidity and minimal deformation under heavy braking loads
• Hard Anodized Finish: Caliper body is hard anodized for long-term corrosion resistance and durability at elevated operating temperatures
• Drilled 2-Piece Floating Rotor: Oversized two-piece disc assembly with an exclusive vented design that improves cooling capacity and increases resistance to thermal shock cracking by over 40%
• Cross-Drilled Surface: Precision-drilled holes dissipate heat, clear brake dust and gases, and maintain consistent pad-to-rotor contact
• High-Performance Brake Pads: Included pads are formulated with specific friction materials matched to the rotor and caliper combination
• Complete Hardware Kit: Includes all necessary brackets, mounting adapters, and high-quality fasteners for a direct installation
• 2-Year Warranty: Backed by Brembo's standard two-year warranty for GT series big brake kits

The GT-S system sits at the top of Brembo's street-performance lineup, offering the opposed-piston caliper technology and oversized rotor geometry that provide noticeably shorter stopping distances, improved pedal feel, and sustained fade resistance under repeated hard braking.
