Brembo 2M3.9005AS GT-S Rear Big Brake Kit 380x32mm 6-Piston Type-3 Slotted

Brembo GT-S Series Rear Big Brake Kit

The Brembo 2M3.9005AS GT-S system is a professional-grade rear brake upgrade featuring 6-piston cast monobloc calipers with 380x32mm 2-piece discs and hard anodized caliper finish. This complete rear axle brake kit delivers motorsport-derived performance for demanding track and street applications.

Premium Cast Monobloc Calipers

The calipers are hard anodized for longevity and resistance to corrosion at high temperatures. Featuring radial mount construction, these 6-piston calipers provide exceptional clamping force with precise brake modulation and minimal deflection under extreme braking loads.

Advanced 2-Piece Disc Design

Systems come with opposed piston calipers and are designed for high thermal resistance and precise brake modulation. Lightweight 2-piece discs increase thermal capacity to dramatically reduce brake fade. The floating disc-to-hat mounting utilizes D-bobbin fasteners with anti-rattle springs for secure, quiet operation.

Type-3 Slotted Performance

The Type3 (TY3) slots ensure cleaning and constant renewal of the pad's friction material, thus guaranteeing consistent performance even during repeated braking. Type 3 introduces variable patterns (size, curvature, length, and orientation) developed from GT endurance racing to continuously refresh the pad surface and maintain optimal bite characteristics.

Complete System Includes

• 6-piston cast monobloc radial mount calipers with hard anodized finish
• 380x32mm 2-piece vented discs with Type-3 slotted pattern
• High-performance brake pads
• Stainless steel braided brake lines
• CNC-machined caliper mounting brackets

Important Installation Notes

Not for road use. This system eliminates the parking/emergency brake function. Professional installation required. Designed for original ride height vehicles. The Type-3 configuration is intended for racing applications where maximum braking performance is required.

Note: This is a rear axle system designed for track use. Ships pre-assembled for convenient installation.
