Brembo 1ND.9521A3 GT Series Big Brake Kit Slotted Rotor Caliper - 405mm 2-Piece 6-Piston Silver

The Brembo 1ND.9521A3 is a GT Series Gran Turismo Big Brake Kit engineered for drivers who demand race-inspired stopping power for both street and track use. This front brake kit pairs a large-diameter 405mm x 34mm slotted 2-piece floating rotor with a 6-piston monobloc aluminum caliper finished in silver, delivering a dramatic upgrade in braking performance and visual presence.

Key Features:

• 6-Piston Monobloc Caliper: Machined from a single billet of cast aluminum for exceptional rigidity and minimal deformation under heavy braking loads
• 405mm x 34mm 2-Piece Slotted Floating Rotor: Large-diameter vented disc with slotted surface for improved heat dissipation, gas evacuation, and consistent bite
• 2-Piece Floating Disc Design: Aluminum alloy bell reduces unsprung weight and accommodates thermal expansion, improving fade resistance and rotor longevity
• Silver Caliper Finish: High-visibility silver powder coat with embossed Brembo logo for a premium aesthetic behind the wheel
• High-Performance Brake Pads Included: Purpose-matched friction material optimized for the GT Series caliper and rotor pairing
• Stainless Steel Braided Brake Lines: Included for improved pedal feel and pressure consistency over stock rubber lines
• Aircraft-Grade Mounting Hardware: CNC-machined billet caliper adapter brackets and all necessary fasteners included for a complete installation
• ABS and OEM Master Cylinder Compatible: Designed to bolt onto the vehicle's original suspension without modifications to the hydraulic system

Brembo's GT Series kits are developed from decades of Formula 1 and motorsport engineering, offering a proven path to shorter stopping distances, improved pedal modulation, and superior fade resistance under repeated high-stress braking.
