Brembo 2S3.9008A7 GT Rear Big Brake Kit 380x28mm 2-Piece Slotted Disc BM4 4-Piston Fluorescent Yellow Caliper

The Brembo GT Series brake system features aluminum calipers with radial mounting and opposed pistons for even brake force distribution, greater stiffness, and uniform pad wear, paired with oversized 2-piece composite discs specifically engineered for enhanced performance. This rear axle kit includes 380x28mm (15.0" x 1.1") slotted Type 3 rotors and advanced BM4 monobloc calipers in eye-catching fluorescent yellow.

Advanced BM4 Caliper Technology:

• Manufactured using an innovative 4D casting process—the first time this technology has been used for automotive calipers—resulting in a completely different design with technical features normally found only on racing calipers machined from billet or forged
• Cast with internal fluid lines rather than conventional external rigid pipe connections, with an invisible bleeding screw that provides greater safety and a cleaner design
• 4-piston monobloc caliper design suitable for rear axle applications with discs up to 380mm x 30mm
• Fixed caliper design with several opposed pistons allows enhanced distribution of pad action and more uniform wear on friction surfaces

Type 3 Slotted Rotor Benefits:

• Type 3 slotted finish continuously refreshes the pad surface, removing debris and impurities while ensuring a stable friction coefficient
• 2-piece floating design reduces unsprung weight and increases brake torque, with cast iron disc attached to precision-milled billet aluminum center section
• Exclusive ventilation system optimizes cooling and increases resistance to thermal shock, ensuring greater safety and extended durability
• Floating hardware allows the disc to expand and contract according to temperature variations in both radial and axial directions

Complete Kit Includes:

• Pair of BM4 4-piston monobloc aluminum calipers in fluorescent yellow
• 380x28mm 2-piece slotted Type 3 rotors (15.0" diameter)
• High-performance brake pads optimized for maximum grip, braided stainless steel hoses, adapters, and high-quality mounting hardware
• Fully compatible with factory master cylinder, ABS, and traction control systems

This system delivers more immediate and decisive braking that's noticeable during normal road use while remaining incredibly powerful and consistent during track days. The radial-mounted design and oversized rotors provide increased braking torque and greater thermal capacity for fade-free performance.
