Brembo 2P3.9069AS GT-S Rear Big Brake Kit 380x28mm 2-Piece Slotted Type 3 Discs Black Hard Anodized M4 4-Piston Calipers

The Brembo 2P3.9069AS GT|S Rear Big Brake Kit is a complete, motorsport-derived braking upgrade featuring 380x28mm 2-piece composite rotors paired with hard anodized black M4 4-piston monobloc calipers. Engineered as the bridge between road and track performance, the GT|S series delivers a decisive step toward high-level braking capability for demanding drivers and track day enthusiasts.

Type 3 Slotted Disc Technology:

• Type 3 (TY3) curved slotted finish continuously refreshes the pad surface, removing debris and impurities while maintaining a stable friction coefficient
• Aggressive curved machined slots provide maximum cooling, degassing, enhanced pedal bite, and superior feel and modulation
• 2-piece floating disc construction increases thermal capacity to dramatically reduce brake fade under sustained high-load braking
• Exclusive internal venting system improves cooling capacity and increases resistance to thermal shock cracking by over 40%

M4 Monobloc Caliper Features:

• Hard anodized black finish for enhanced longevity and corrosion resistance at elevated operating temperatures
• Cast monobloc construction machined from a single billet of aluminum ensures outstanding rigidity with minimized deformation under hard braking
• 4-piston opposed design with radial mounting for even brake force distribution, greater stiffness, and uniform pad wear
• Racing-style Brembo logo engraved in red, as found on Brembo's competition products

Complete Kit Includes:

• 380x28mm 2-piece Type 3 slotted rear rotors (pair)
• Hard anodized black M4 4-piston monobloc aluminum calipers (pair)
• Application-specific high-performance brake pads (Brembo FM1000 compound)
• TUV/DOT homologated stainless steel braided brake hoses
• CNC billet caliper adapter brackets and all required mounting hardware

The Brembo GT|S series represents Brembo's most complete street-to-track upgrade package, combining motorsport-proven technology with the reliability and drivability required for spirited road use. This kit is backed by Brembo's 2-year limited warranty against manufacturing defects.
