Wilwood 120-16891 Forged Six Piston Disc Brake Caliper - Aero6

The Wilwood Aero6 forged six piston caliper (PN 120-16891) delivers heavy-duty stopping power engineered for both street and track applications. Designed for high-performance vehicles requiring maximum braking force, this caliper features radial mounting and accommodates rotor diameters ranging from 12.88" to 15.00", providing the versatility needed for demanding braking requirements.

Advanced Forging Technology:

The Aero6 caliper body is stress-flow forged from premium-grade aluminum alloy billet. This specialized forging process realigns the metal's internal grain structure to flow naturally within the contour of the caliper body, eliminating the internal stresses and grain interruptions that occur with conventional straight-block billet machining. The result is a caliper with superior clamping efficiency, exceptional strength-to-weight ratio, and ultimate resistance to fatigue, stress, and distortion under extreme braking loads.

Key Features:

• Six-piston design for increased pad pressure and consistent clamping force
• Stress-flow forged aluminum construction for maximum strength and durability
• Radial mounting configuration for improved structural rigidity
• Compatible with rotor diameters from 12.88" to 15.00"
• Multiple piston volume options available for brake bias tuning
• Engineered for heavy-weight vehicles and high-performance applications

This caliper is ideal for performance upgrades on muscle cars, sports cars, trucks, and race vehicles requiring enhanced stopping power and fade resistance.
