Brembo 1J3.9027A3 GT Series Big Brake Kit - 380mm 6-Piston Silver

The Brembo 1J3.9027A3 GT Series Big Brake Kit is a complete, race-inspired front braking upgrade engineered for drivers who demand superior stopping power, fade resistance, and precise pedal feel. This kit replaces the OEM braking system with Brembo's motorsport-derived components, delivering dramatically improved thermal capacity and braking consistency under repeated hard stops.

Key Features:

• 6-Piston Monobloc Aluminum Calipers: Cast monobloc construction machined from a single billet of aluminum ensures outstanding rigidity and minimal flex under high-load braking. Finished in silver with corrosion-resistant plating for long-term durability.
• 380mm x 34mm 2-Piece Floating Rotors: Oversized two-piece composite rotor design features an aluminum alloy hat to reduce unsprung weight and thermal stress. The floating mount allows greater radial and axial movement to minimize heat transfer to the hub.
• Cross-Drilled and/or Slotted Rotor Surface: Precision-drilled and slotted braking surfaces evacuate heat, gas, and debris from the pad-rotor interface, maintaining consistent bite and reducing brake fade during sustained performance driving.
• Exclusive Venting System: Brembo's proprietary internal venting geometry increases cooling capacity and improves resistance to thermal cracking by over 40% compared to standard rotors.
• Metal Braided Brake Hoses: Included stainless steel braided hoses minimize fluid expansion under pressure, delivering a firmer, more consistent brake pedal with improved modulation.
• High-Performance Brake Pads: Kit includes performance brake pads engineered to complement the oversized rotor and caliper combination for aggressive initial bite and consistent fade-free performance.
• Complete Hardware Kit: All necessary mounting hardware, brackets, and caliper adapters are included for a complete front axle installation.

The Brembo GT Series big brake kit is designed and tested for both street and track use, making it equally capable during demanding track day sessions and everyday high-performance driving. The opposed multi-piston caliper design distributes clamping force evenly across the pad surface, resulting in more uniform pad wear and extended service life. Backed by Brembo's industry-leading engineering and a 2-year warranty against material and workmanship defects.
