Brembo 2PD.9034AS GT-S Series Big Brake Kit Slotted Rotors - 4-Piston 380x34mm 2-Piece

The Brembo 2PD.9034AS GT-S Series Big Brake Kit is a complete, high-performance braking upgrade engineered for drivers who demand exceptional stopping power on both the street and the track. Part of Brembo's renowned Gran Turismo (GT-S) system lineup, this kit delivers motorsport-derived braking technology in a complete, bolt-on package.

At the heart of this kit are fixed 4-piston aluminum calipers with opposed pistons, designed for high thermal resistance and precise brake modulation. The calipers feature racing-style piston radiators and dual inner piston seals—an inner pressure seal and an outer wiper seal—for optimal performance and longevity under repeated high-heat braking.

The kit includes 380x34mm 2-piece floating slotted brake discs, constructed from a proprietary cast iron alloy for superior durability. The cast iron rotor ring is mounted to a precision-milled billet aluminum center hat using Brembo's floating "bobbin" hardware, which allows the disc to expand and contract thermally without warping. The slotted rotor surface continuously cleans and refreshes the brake pad face, evacuates gases and debris, and resists fade under extreme conditions.

Key Features:

• Fixed 4-piston aluminum calipers with hard anodized finish for corrosion resistance
• 380x34mm (15-inch) 2-piece floating slotted brake rotors
• Proprietary cast iron alloy rotor construction for extended service life
• Billet aluminum rotor center hat reduces unsprung rotating weight
• Floating D-bobbin mounting system accommodates thermal expansion
• Directionally vented rotor design improves cooling capacity and increases resistance to thermal cracking by over 40%
• Includes high-performance Brembo brake pads with race-proven friction material
• DOT/TÜV-approved Goodridge stainless steel braided brake lines included
• Aircraft-quality CNC-machined caliper mounting brackets and all installation hardware included
• Fully compatible with OEM ABS and traction control systems
• Backed by Brembo's 2-year warranty against manufacturing defects

The Brembo GT-S system bridges the gap between street and track performance, offering fade-free braking with improved pedal feel and modulation. The complete kit includes calipers, rotors, brake pads, braided brake lines, mounting hardware, and installation instructions—everything needed for a direct, professional installation.
