Brembo 1ND.9058A3 GT Series Big Brake Kit 380x34mm 6-Piston Silver Caliper

The Brembo 1ND.9058A3 is a GT Series Big Brake Kit featuring a 380mm x 34mm 2-piece slotted rotor paired with a cast monobloc radial-mounted 6-piston caliper finished in silver. Part of Brembo's renowned Gran Turismo (GT) performance upgrade line, this kit is engineered to deliver a significant step up in braking performance over stock systems for both spirited street driving and track use.

Key Features:

• 380mm x 34mm 2-Piece Floating Disc — Oversized rotor dramatically increases braking surface and thermal capacity compared to OEM
• 6-Piston Cast Monobloc Caliper — Silver Finish — Machined from a single cast aluminum billet for exceptional rigidity and minimal flex under heavy braking loads
• Radial Caliper Mounting — Provides maximum structural stiffness and precise, consistent pedal feel
• Slotted Rotor Design — Continuously sweeps debris and gases from the pad surface for improved bite and consistent friction
• 2-Piece Floating Rotor Construction — Aluminum alloy hat reduces unsprung weight and allows radial and axial float to manage thermal expansion and reduce rotor stress
• High-Performance Brake Pads Included — Kit ships with Brembo GT-grade performance pads matched to the caliper and rotor specification
• Metal-Braided Brake Hoses & Hardware Included — All necessary mounting hardware, CNC billet caliper adapters, and stainless steel braided brake lines are included for a complete installation
• Ships Pre-Assembled — Caliper and rotor assembly arrives ready to install

Brembo GT Big Brake Kits are developed from decades of motorsport engineering experience. The monobloc caliper design ensures outstanding rigidity under repeated high-load braking events, while the 2-piece floating disc construction improves heat dissipation and reduces the risk of thermal cracking and brake fade. The silver caliper finish provides an aggressive, high-visibility appearance behind the wheel.
