Brembo 2P2.9063AR GT-R Rear Big Brake Kit with M4 4-Piston Calipers and 380x28mm Slotted Rotors

The Brembo GT-R Series brake kit is specifically designed and tested for track day enthusiasts and drivers who demand exceptional rigidity, reduced deformation, and superior performance for both road use and demanding track sessions. This rear brake system features premium nickel-plated M4 calipers paired with 380x28mm two-piece slotted rotors for maximum stopping power and thermal management.

M4 Billet Monoblock Calipers:

• Machined from billet aluminum with radial 4-piston design for exceptional strength and rigidity
• Nickel-plated finish derived from Formula 1 racing calipers for superior corrosion protection and refined machining tolerances
• Pistons feature stainless steel radiators that significantly reduce heat transmission to brake fluid during extreme driving
• M4 calipers accommodate disc sizes from 328mm to 380mm and are perfect for rear axle applications
• Brembo logo is CNC machined in red embossing for authentic racing aesthetics

Two-Piece Floating Disc System:

• Two-piece floating disc design reduces unsprung weight and dissipates heat quickly
• 380x28mm slotted rotors (Type 1 slotting pattern) provide consistent performance and improved pad bite
• Unique ventilation system improves cooling capacity and increases resistance to thermal cracking by over 40%
• Mounting system engineered to permit greater radial and axial float for reduced thermal stress

Complete Kit Includes:

• Pair of M4 4-piston billet monoblock calipers with nickel-plated finish
• 380x28mm two-piece slotted floating discs (Type 1)
• High-performance brake pads
• Stainless steel braided brake lines
• CNC machined billet caliper mounting brackets and hardware

Experience more responsive, decisive braking with improved pedal feel and modulation thanks to exceptional caliper rigidity and reduced brake fluid absorption. This GT-R system delivers professional-grade performance and reliability proven at the highest levels of motorsport competition.
