Brembo 2SD.9021A2 GT Series Rear Big Brake Kit with 2-Piece Slotted Rotors

The Brembo 2SD.9021A2 is a complete rear axle Big Brake Kit from Brembo's renowned GT (Gran Turismo) Series, engineered for drivers who demand race-proven stopping power on the street and track. This kit pairs large-diameter 2-piece vented slotted rotors with high-performance multi-piston calipers for a dramatic upgrade over OEM braking hardware.

Key Features:

• GT Series 2-Piece Slotted Rotors: Manufactured from Advanced High Carbon Alloy with a corrosion-resistant plating finish; slotted rotor design improves pad bite, reduces brake fade, and provides an escape channel for water, gas, and brake dust
• Multi-Piston Cast Monobloc Calipers: Lightweight aluminum construction delivers firmer pedal feel and superior clamping force compared to stock single-piston sliding calipers
• Brembo FM1000 High-Performance Brake Pads: Proprietary compound engineered for excellent initial response, strong modulation, and consistent feel across a wide range of temperatures — from daily street driving to track events
• Stainless Steel Braided Brake Lines: Proprietary Brembo lines by Goodridge, DOT/TÜV approved, for improved pedal firmness and hydraulic response
• CNC Billet Caliper Mounting Brackets: Vehicle-specific brackets for precise fitment and optimal brake balance
• Floating Bobbin Disc-to-Hat Mounting: Anti-rattle bobbins allow the rotor ring to float, reducing heat transfer to the hub and minimizing thermal distortion
• Fully Compatible with OEM Systems: Designed to integrate seamlessly with the vehicle's stock master cylinder, ABS, and traction control systems
• Complete Hardware Included: All necessary anti-rattle hardware, fasteners, and installation components are included for a straightforward installation

Brembo GT Big Brake Kits are engineered to increase thermal capacity and reduce the risk of brake fade under repeated heavy braking. The system can also reduce unsprung weight compared to heavy OEM cast iron assemblies, contributing to improved handling and suspension response. This rear kit is intended to complement a Brembo GT front brake system for balanced, high-performance braking at all four corners.
