Wilwood 120-16893 Aero6 Radial Mount 6-Piston Disc Brake Caliper

The Wilwood Aero6 Radial Mount Caliper (120-16893) is a high-performance, six-piston forged aluminum brake caliper engineered for demanding road and track applications. With radial mounting geometry, multiple piston volume options, and compatibility with rotor diameters ranging from 12.88" to 15.00", this caliper delivers the versatility required for a wide range of heavy-duty braking setups.

Key Features:

• Six-Piston Design: Provides exceptional clamping force and even pad pressure distribution across the rotor surface for consistent, fade-resistant stopping power
• Stress-Flow Forged Aluminum Body: The caliper body is forged from a premium-grade aluminum alloy billet using Wilwood's stress-flow forging process, which realigns the metal's internal grain structure to follow the contour of the caliper — eliminating the stress points introduced by traditional straight-block billet machining
• Superior Structural Integrity: The stress-flow forging process results in a caliper with outstanding clamping efficiency and enhanced resistance to fatigue, stress, and distortion under high load conditions
• Radial Mounting: Radial mount configuration provides a stiffer, more precise brake feel and simplifies installation on purpose-built and performance street applications
• Multiple Piston Volume Options: Available in various piston configurations to optimize pedal feel and braking bias for your specific application
• Wide Rotor Compatibility: Supports rotor diameters from 12.88" to 15.00", making this caliper suitable for a broad range of performance braking packages
• Lightweight Construction: Forged aluminum construction minimizes unsprung weight while maintaining maximum structural strength

The Wilwood Aero6 caliper is an ideal choice for high-performance street machines, road racing, and track-day vehicles that demand reliable, heavy-duty braking performance. It is part of Wilwood's proven Aero series, trusted by professional and amateur racers alike.
