Brembo 1N3.9539A3 GT Big Brake Kit 405x34mm 2-Piece Front Rotors Silver Calipers

The Brembo 1N3.9539A3 GT Big Brake Kit delivers race-proven stopping power and heat management for high-performance driving. This complete front brake upgrade features massive 405x34mm two-piece slotted Type-3 rotors paired with Brembo's legendary silver-finished aluminum calipers.

Key Features:

• 405x34mm two-piece floating rotors with Type-3 slotted design for superior heat dissipation and reduced brake fade
• High-performance aluminum calipers with silver finish and Brembo GT branding
• Six-piston (M6) caliper design for maximum clamping force and even pad wear
• Slotted rotor surface helps evacuate brake dust and gases while maintaining pad bite
• Two-piece rotor construction reduces unsprung weight and allows for thermal expansion
• Direct bolt-on application for BMW 5-Series (G30) 540i and 540i xDrive models
• Fits vehicles with 17-inch or larger wheels (excluding M-Sport brake equipped models)
• Complete kit includes rotors, calipers, high-performance brake pads, and all necessary hardware

Brembo GT Systems represent the pinnacle of aftermarket brake performance, combining decades of motorsport engineering with street-friendly durability. The larger rotor diameter and increased thermal mass provide dramatically shorter stopping distances and consistent pedal feel during aggressive driving. Professional installation recommended.
