Brembo 1N3.9007A1 Gran Turismo GT Big Brake Kit - Black Calipers

The Brembo Gran Turismo (GT) Big Brake Kit (PN: 1N3.9007A1) is a complete, motorsport-derived high-performance braking system engineered for demanding street and track use. Featuring oversized calipers and discs, the GT kit dramatically increases thermal capacity and brake torque far beyond what a standard OEM system can deliver.

Two-Piece Rotor System:

• Aluminium radial-mounted fixed calipers with sequentially sized opposing pistons — available in 2, 4, 6, or 8-piston configurations depending on application
• Caliper color: Black (1N3.9007A1); also available in Red (A2) and Silver (A3)
• Two-piece "floating" hat-and-rotor assemblies with a cast-iron disc mounted to a billet aluminum hat — reduces unsprung and rotating weight while accelerating heat dissipation
• Cross-drilled or slotted two-piece discs up to 16" (405 mm) depending on application
• Brembo high-performance brake pads included
• DOT/TÜV-approved Goodridge stainless steel braided brake lines
• Billet CNC caliper mounting brackets and aircraft-quality assembly hardware
• Floating anti-rattle disc hardware included
• Most GT applications carry TÜV certification
• Fully compatible with ABS and traction control systems

One-Piece Rotor System (select applications):

• 2 or 4-piston calipers with sequentially sized pistons; caliper color choices of Black, Red, or Silver
• Cross-drilled or slotted one-piece discs up to 14" (355 mm)
• DOT/TÜV-approved stainless steel braided brake lines
• Brembo high-performance brake pads
• Billet caliper mounting brackets
• Most GT applications carry TÜV certification
• Fully compatible with ABS and traction control systems; all necessary hardware included

Important: Proper wheel clearance is critical for fitment of any Brembo GT brake system. Always verify that your wheels provide adequate caliper and rotor clearance before installation. Some applications may require modification or removal of the OEM dust shield or backing plate.
