• Brembo multi-piston calipers (2, 4, 6, or 8 pistons depending on application) with sequentially sized pistons for balanced brake force distribution
• Two-piece floating hat and rotor assemblies that reduce unsprung and rotating weight while enhancing heat dissipation
• Drilled or slotted rotors available up to 16 inches (405mm) in diameter
• Choice of red, black, or silver caliper finish
• DOT/TÜV approved stainless steel braided brake lines
• High-performance brake pads engineered specifically for the system
• Floating anti-rattle hardware for quiet operation
• Precision-machined billet aluminum caliper mounting brackets

One-Piece Rotor Applications Include:

• Brembo 2 or 4 piston calipers with sequentially sized pistons
• Drilled or slotted one-piece rotors up to 14 inches (355mm)
• DOT/TÜV approved stainless steel braided brake lines
• High-performance brake pads
• Billet aluminum caliper mounting brackets
• Choice of red, black, or silver caliper finish

Most Gran Turismo kits include TÜV certification and are fully compatible with ABS and traction control systems. Complete hardware is included for seamless installation. Proper wheel clearance measurement is critical for fitment—verify your wheel specifications before installation.
