Brembo 1MD.9047AS GT-S Series Big Brake Kit with Rotors - 2-Piece

The Brembo 1MD.9047AS is a GT-S Series Big Brake Kit engineered for drivers who demand race-derived stopping power for aggressive street and track use. Part of Brembo's renowned Gran Turismo S (GT-S) upgrade lineup, this kit delivers a significant leap in braking performance over stock systems through motorsport-derived components and precision engineering.

At the heart of the GT-S system are cast monobloc, radially mounted aluminum calipers derived from the Brembo M-Series racing caliper family. The hard anodized caliper body features racing-style piston radiators and dual inner piston seals — an inner pressure seal and an outer wiper seal — for exceptional heat management and long-lasting performance even under sustained high-load braking. The iconic Brembo logo is engraved in red, consistent with the brand's competition products.

Key Features:

• GT-S Series cast monobloc radial-mount caliper body with hard anodized finish
• Racing-style piston radiators with dual inner piston seals for superior heat control
• 2-piece floating rotors constructed from proprietary high-carbon alloy for extended durability
• Floating bobbin mounting hardware allows radial and axial disc expansion under thermal cycling
• Anti-rattle disc hardware eliminates noise associated with floating rotor designs
• Vented rotor design for improved airflow and resistance to brake fade
• Corrosion-resistant plating on rotor surfaces for long-term durability
• Includes high-performance brake pads, mounting brackets, and all necessary hardware
• Compatible with OEM ABS and traction control systems

The 2-piece floating rotor design reduces unsprung weight compared to conventional one-piece rotors, improving suspension response and overall vehicle dynamics. Brembo's proprietary bobbin fasteners allow the cast iron disc to expand and contract freely with temperature changes, reducing the risk of thermal warping and cracking over time.

The Brembo GT-S Big Brake Kit ships pre-assembled and includes all hardware required for installation. It is designed and tested to meet both street and track-day demands, offering improved pedal feel, better brake modulation, and consistent fade resistance that stock brake systems cannot match.
