• Two-piece floating hat and rotor assemblies reduce unsprung and rotating weight while improving heat dissipation
• Drilled or slotted rotors available in sizes up to 16 inches (405mm) for maximum thermal capacity
• Available in red, black, or silver caliper finishes

One-Piece Rotor Configuration:

• Cost-effective brake upgrade with 2 or 4 piston calipers featuring sequentially sized pistons
• Drilled or slotted one-piece rotors up to 14 inches (355mm)
• Available in red, black, or silver caliper finishes

Complete Kit Includes:

• High-performance brake pads formulated for aggressive stopping power
