Wilwood 120-16891-BK Forged Disc Brake Caliper - Aero6 6-Piston Black

The Wilwood Aero6 Forged Six-Piston Disc Brake Caliper (120-16891-BK) delivers serious stopping power for both street and track applications. With radial mounting, multiple piston volume options, and compatibility with rotor diameters ranging from 12.88" to 15.00", the Aero6 offers the versatility needed to meet demanding, heavy-duty braking requirements.

Stress-Flow Forged Aluminum Construction:

The Aero6 caliper body is stress-flow forged from a premium-grade aluminum alloy billet. Unlike conventional machined billet calipers, the stress-flow forging process realigns the metal's internal grain structure to follow the contour of the caliper body. This eliminates the stress concentrations and grain interruptions caused by straight-block machining, resulting in a caliper with superior clamping efficiency and exceptional resistance to fatigue, distortion, and stress under load.

Key Features:

• Six-piston forged aluminum caliper for high-clamping force and lightweight performance
• Radial mounting design for precise, rigid caliper positioning
• Compatible rotor diameter range: 12.88" to 15.00"
• Multiple piston volume options for tunable pedal feel and brake bias
• Stress-flow forged construction eliminates internal grain interruptions for superior strength
• Black anodized finish for corrosion resistance and appearance
• Ideal for heavy-duty street and high-performance track applications

The Wilwood Aero6 caliper is engineered for performance builds that demand maximum braking reliability and consistent feel under repeated high-heat cycling. It is a proven choice for road racing, track day, and high-performance street builds requiring a robust, six-piston braking solution.
