Brembo 1ND.9521AR GT-R Series Big Brake Kit Rotors - 6-Piston 405mm 2-Piece

The Brembo 1ND.9521AR is a complete GT-R Series Big Brake Kit engineered for drivers who demand race-derived stopping power. Part of Brembo's flagship GT-R line, this big brake kit (BBK) features a 6-piston billet monobloc radial-mounted caliper paired with 405mm x 34mm 2-piece floating discs to deliver exceptional thermal capacity and fade resistance under repeated high-performance use.

Key Features:

• 6-Piston Billet Monobloc Calipers — Machined from a single billet of aluminum for maximum rigidity and minimal deformation under heavy braking loads
• 405mm x 34mm 2-Piece Floating Rotors — Reduces unsprung weight and allows radial and axial float to dissipate heat more effectively and resist thermal cracking
• Nickel-Plated Caliper Body — Provides long-term corrosion resistance with CNC-machined Brembo logo embossing for a premium appearance
• Individual Stainless Steel Piston Radiators — Significantly reduces heat transfer to brake fluid, minimizing fade and extending pad life during aggressive driving
• High-Performance Brake Pads Included — Friction compounds engineered to outperform OEM pads in both street and track conditions
• Ships Pre-Assembled — Complete kit includes CNC billet caliper adapters, stainless steel braided brake lines, and all necessary installation hardware

Brembo's GT-R Series Big Brake Kits are developed from decades of motorsport engineering experience, drawing directly from Formula 1 and MotoGP programs. The 2-piece floating disc design features an exclusive venting system that improves cooling capacity and increases resistance to cracking caused by thermal shock. The result is consistent, predictable pedal feel and braking force whether on the street or the track.
